Trying to get relief.

Hi everyone. This is my first post. I'm 22yo. not on medication.I have extreme social anxiety. and something else. from I wake up until I sleep i became obsessed on how will fix myself from the inside and to accept my self so I can move forward in life, which is really tiring me to the point that gets me suicidal sometimes. could it be GAD? I've also experienced derealazation which really frightens me and Im scared that it would kick in again and I'm having troubles viewing the world in a clear way.I have been also diagnosed with ADD but i feel there is something really wrong with me.
If you have time this is my story

I am the eldest in a religious family to two siblings. to an egoistic father and a people pleasing mother. "who are both wonderful in a way" My sister is the reliable one and my young brother is the smart one who you can never win an argument with and I'm the creative one in a way. However. I went to a religious school when I was 8 until I was 14 where I used to get beaten up by a sadistic teacher almost weekly for just not doing my homework. However, I used to get bullied alot when I was younger and pathetically of me I still wanted to hang out with the cool kids and like them even when they treated me badly and I feel I had no dignity at all. anyways after finishing highschool I went to study abroad in Ireland where everythng was almost different, I lost my religion, my aspects of life have changed. I became addicted to weed because I thought it was cool and it will help me get laid "which it didnt so far", however after a while of smoking I knew this guy who never smoked but he wanted to smoke. so he invited me to his house so we can smoke up together. however after a few joints he got paranoid and thought that I was going to rob his place lol so he called his friends who came and they beat me up. I was really scared and didnt know how to react. However, after the incident I was having PTSD for 3 or 4 months. However I became more addicted to weed afterwards and started view the world differently, I thought no one was really happy and everyone is just trying to impress everyone. and everyone has a really deep side inside of them that makes me uncomfortable. However at the end of the first year in college I failed all the subjects and when I went back to and my parents and my nature of relationship changed with everyone. I had a breakdown when I realised that my pattern of thinking was wrong and there is real happiness in life. However a year have passed and now Im still having troubles trusting my thoughts again, since I wake up till I sleep Im just trying to find a solution to my problem, its like im trying to fix myself from the inside. Im reading about buddhism and stuff and became obsessed with it
I also daydream alot how my life would be perfect and how Ill have a great personality.

However,
my recovery plan so far is to get into MMA. Do meditation regularly and do a course on NLP and do CBT. what do you think?

could it be GAD?

Yes it could, however are labels really that important? Besides, it is hard to get an opnion on the internet, besides diagnosing being not allowed on the forum.

Find a CBT therapist, they will give you much better advice. What you mean by MMA, martial arts? They may help with getting in touch with body, if that is the problem.
