I need help

Hi, I'm an 18 year old male diagnosed with clinical depression. I believe that this depression is hereditary since both of my parents seem to be the same way as I am. I'm not sure what else I have that's why I came here to seek help.

I was a very outgoing, social, healthy, overall happy and normal child. I had many interests and was very active in many sports. I was always very good in school, getting great grades and respect from all of my teachers. I've been told through out the years that I am very intelligent,smart,mature, well manured, friendly, nice, ect. As I got older however, I gradually lost interest in everything including all of the sports that I played and became very isolated and depressed.

I started skipping school in 7th grade missing literally half the year every year until 10th grade when I had a probation officer monitoring my attendance and was told if I don't go, I'll be put in probation. So after the first semester of 10th grade I dropped out of school, and received my GED.

I lost all my friends because of this. I never socialized while I was going to school for the period of time that I was constantly skipping school. So I resorted to playing video games and started listening to angry and depressing music. I started wearing black and band shirts and therefore was outcasted in the school which might have been part of why I didn't want to socialize. I've had many crushes but was never confident to do anything more about them.

I eventually got a job at 17 where the majority of the workers were in my age group. I had problems adjusting, everyone wanted me to socialize with them but I was in my own protective shell. I was taking anxiety meds ( I also have bad anxiety, including social anxiety) and eventually started socializing, being myself, joked around, ect and everyone started liking me. I made friends easily and what not and then came along a new girl that seemed very interested in me. She was very attractive, intelligent, nice, ect. To some it up I was intoxicated over the mere thought of her, and I started to fall for her hard. To save all the details, she wasn't who I thought she was and she basically tore my heart out. I have never felt this heartbreaking feeling so overwhelming that I wanted to kill myself. I started drinking very heavily because of this. I was know as the drunk/alcoholic at work after I broke out of my shell because I had a friend at work that I would buy alcohol from weekly, hence the label. As time progressed, I stopped taking all of my meds, started to smoke cigarettes, started to smoke marijuana, and drank heavily.

As of now I have completely stopped smoking pot, I drink rarely, and I'm up to almost a pack a day of cigarettes. I don't exercise anymore or socialize (I am literally in contact with no one except for my parents). I literally just go to work, come home and play video games or watch Tv/movies, go to sleep, and repeat. I am always tired regardless of how much sleep I get, I have no appetite, I have a porn/ masturbation addiction, I feel useless, have no confidence, low self esteem, never happy. I think that I have symptoms of the following personality disorders: Paranoid, Schizoid, Schizophrenia. I know I have written alot but I just wanted to put in some background information to see if anyone can give an assumption as to why I am this way.

i was going to go ahead with my ussual check for candida but you show some symptoms yet also no appetite which isnt really a symptom.Ussually you would be hungry for snacks.
What is it you would like to get out of life?
I think having goals or aspirations really helps to motivate us to move forward and then once we are moving we can then choose which way and how to go about it.
Alot of the problems you see in yourself i also have still or had.Its not so uncommon that you are alone there
I also have more or less given up smoking weed.It does sapalot of motivation to go and get things done.So until i was able to fix that i decided to give it a rest for now.
I think for someone your age or any actually, exercise is important to combat low moods.My first task i set myself when i decided to change my life and way of thinking was to go for a 30 min - 3 hour walk around the city where i live with my mp3 player for company.It gives me time to mull thngs over,get some confidence and feel stronger once i get regular.The chemicals exercise produce have been known to be addictive as it does improve your mood.I think its endorphines but cant remember.
You are still so young and have so much time it to discover what you want to do.I am 30 now and still unsure which path to take.I spent time procrastinating,being ill without kowing it and then obsessed with my own issues to live my life or even discover what i want.
I would recoment not consiging yourself to the idea that you will be depressed because your parent seem to be. was diagnosed with clinical depression,seasonal aafective disorder etc etc but all i had was a yeast overload and a lashback psychologically from being involved with a cult like religion.It took me about 6 years at least from my worst point to realise i can alot of stuff for myself and i enjoy the journey now more than focusing on the negatives.I have a trick too of being able to convince myself through reasoning that any situation can be taken as good or bad.If i constantly search for the advantage of having such and such a problem/situation i can get around those negative or guilty feelings by reasoning on the positive side.
I may have wanted to die because i was so depressed but now that i have been that low i am much stronger and able to bare these not as lows i experience.Its all how you look and view it.

I used to love judo and karate as a kid but my religious mother wouldnt let me join even a football club let alone a violent one.
Now im 30 and its too late to train to compete for money as you need to start ideally at around 22 or earlier.But im still going to join an mma gym which is something i would never have done before.I want to challenge myself and use my stubborness(which before i thought was a negative) to do this.
So at the young age of 18 what do you think you might like doing or be good at doing? for work and pleasure.
How about a skydiving instructer? a pet trainer, a doctor,vet,entrepeneur,writer,artist,game programmer etc etc pick about 10 things to try out or explore/research and see what you like
Are you a left or right brain thinker? this might help you decide a career path that suits you and makes you happy.
I am a right brain thinker for the most part so i am very creative and have very good spacial awareness.Im suited to jobs which allow me to use my creativity and feel restricted if forced to follow set instructions or linear tasks.
There is just so much good stuff out there for you to start learning about that will totally change your life!
Its hard to see but its all there once you embrace it.
