Need help

I've been told that I have GAD but I feel as if I have been misdiagnosed. I am of 20 years of age and these are my symptoms. I have never been good at explaining things though.
Symptoms:

1. Emotional detachment from those around me (no desire to connect to family, friends or girlfriend)
2. Blackouts: I become full of anger and physically start to shake if I lose control I see myself punch a wall unless I’m in an altercation with another person then I see myself attacking them. No control over what I say (I say things I didn’t even think of or I said something completely different) It’s as if there’s someone else in my body and I’ve been shut out. Afterwards all I feel is anger and I can’t care for those around me, it feels like I’m the only person that exists. I also don’t recognize my own voice.
3. I can’t open up to my family and explain my problems, it feels impossible. This includes doctors.
4. During social occasions I over think what I’m going to say and can dwell on what was said for a long time.
5. I blame myself harshly for any mistakes I made even if I felt as if I said the wrong thing when they understood it fine.
6. I have what I call a mood swing, it can last for hours. I feel completely lost in life and as if there is no future. I can’t feel or remember positive emotions. It feels as if I’ve never been happy before and as if I’ll never be happy again. I see visions of myself causing self-harm and struggle to ignore them. I can’t sleep when this occurs otherwise it gets worse and I break down into tears. During a moods swing my girlfriend playfully said that I was a pussy and I broke out into tears.
7. I often exclude myself from others when I’m stressed or feel anxious, I sit in my room and don’t feel comfortable leaving.
8. I struggle to start conversations with friends; this often leads to me staying in my room for a period of roughly a week. Sometimes it would last longer.
9. Sometimes no matter what I do I cant be entertained, it’s the feeling of constant boredom and not being able to decide what I want to do.
10. I struggle to make decisions for myself, if I’m in a down mood it feels impossible to decide.

I don't know if you have been completely misdiagnosed, maybe under-diagnosed.

You sound like you have GAD and may be bi-polar. Perhaps a little psychosis in there???

I am no doctor, I just know a couple of people just like you...one of them is a family member.

You did a good job explaining your symptoms above....perhaps you should print this out and take it with you to the doctor? I know how difficult it is to actually say what you have been feeling when you are in front of them....you start talking about one thing, and then, before you know it, your time is up.

Thank you for your input, I am seeing a doctor tomorrow and im bringing this list. Hopefully I'll be referred to a psychiatrist without having to wait about 2 months.
