I self harmed for two years. I began starting a new coping skill that has been really effective; eating. Although, I'm worried because I had a slight eating disorder before, eating might draw me back in it agaian.

Im a 19 year old male, believe it or not studying psychology at university. I just cant seem to find myself! I thought university would change this with me living away from home, i thought it would be the part of my life where i would blossom but no, nothings changed.
I have zero confidence, i cant talk to people, i shy away all the time. Ive always been an attractive person, but the exterior just doesnt reflect whats inside. I dont have many friends atall, i know alot of people and people know me but know one that i could actually get into a deep coversation with. One thing that is worrying me alot is the excessive alcohol im drinking, I drink quite often as i believe it gives me more confidence, i am able to conversate with people and actually feel like i have a purpose. Im not an alcoholic as i can take it or leave it but i do feel that if i do not start to get help i will end up turning to drink.
My family is pretty messed up to be honest, my mother is amazing but shes just under so much preassure with work and helping my sister who is a single mother and battleing a cannabis and alcohol addiction. I just dont want to talk to her and put more worries into her head, she wouldnt deal with it. my mother has been on anti-depressents for as long as i can remember.
I feel like i am really blabbing on here but this is the first time ive actually been able to think about the way i feel and what crap is actually in my head. Its getting to the stage where i just dont know which direction i am going in or how to get there. I am not suicidal but the thought has crossed my mind a few times.
I know by writing this im not going to be instantly fixed/cured but it has helped alot, im not asking for answers, just maybe someone to talk to or someone with advice.

Thankyou for taking the time to read this.

This all started about a year and a half ago. I was spending the night at my best friends house for the first time and i got a little warm so i was changing into a tank top and while i had my shirt off his step dad came into the room. i saw him give me a strange glare and walk away. i hadn't thought anything of it for about seven months. Then after noticing that we weren't hanging at his house at all anymore i started wondering. so one day after school i went over to his house. his mom let me in and we talked until he got home. Throughout the this whole time his step dad has blocked my number on their home phone, tried convincing the homeowners community not to allow me to walk on his street, he's banned me from his property, and his son can no longer come over to my house at all anymore. Ive overheard his dad call me a few very unflattering names. and his mom has called my parents a complete waste of time. I'm wondering what options i have either to file a suit against him or how i can get him to understand what he has done over the years.

So i've never written a post ever on any forum, ever, and since things have changed for me recently, i'd decide to give this a go. Might not come back to this but i want to get whats in my head out there and see if anyone has anything to say about me and my problems.
My problems: I care about my family too much. I'm almost certain that I have depression, mild anxiety and a myriad of other mental health problems but I've never been properly diagnosed because I care about my family too much to have them worry about me at all. I also come from a culture where mental health is not a 'real' problem, but rather a thing for the weak or the bored.
I think about death a lot BUT i'm not suicidal. I'm fine with death and i'm not scared of it but I would never be able to go through with it as long as my parents are alive because I can't put them through all that pain. If they died though, I would have not much of a reason to keep going, but that is not the point of this post.
I've always been very aware of my issues and i've always been able to talk myself down in my head like there was a third person that tells the two conflicting voices in my head what to do. This third voice sounds like a trusty friend, insightful parent, or even a advising counsellor, when i think about it. This voice knows what people views as normal and suppresses my arguing voices to make me seem 'normal'. It usually takes effort but I know it works because everyone thinks I'm still this smiley, happy girl, which really hasn't been the case since about 7 years ago (when my first encounter of death in the family happened)
My dog (who's been with me for almost 15 years) died yesterday and I was sad but it wasn't a fearful, regretful sadness. It was more of a "i'll miss you" and "we've spent good time together" happy sadness, though it was really sudden and shocking. I still miss him but I don't think I'm doing too bad. My parents on the other hand haven't been able to sleep, eat, not spontaneously cry, and not talk about morbidity every couple of hours. They also hug me a lot because they think its comforting for me, and probably themselves too.
I guess what I'm saying is that is it weird that I'm so aware of what I'm almost sure I have? Does this mean I don't have these mental health issues because it doesn't really affect my daily life and I know what triggers it, how to control it, and what works/doesn't work? Do other people with mental health issues experience this too?
An analogy (if you're still reading): I deal with my problems like dealing with my period. When it starts, I know what I can do to not let it leak out for the world to see. I know what the best way to deal with the dirty pad/tampon is, to chuck it out (feeling all my feelings/non-feelings but in a physical location where no one will see me then throw them out or at least leave them where they can't be seen). I clean up after myself and flush the bloody mess away (make sure no one can physically see or pick out that I have problems at any point of any time)
What do you think?

Hello! I'm a 19- year old female and I can't seem to say no to sex. I don't feel the urge to constantly have sex but if a guy asks me to have sex I will always say yes. I beat myself up for this so much and I'm not sure if it is a sexual addiction and I don't know how to treat it.
