I can relate my dad is a diagnosed Schitzophrenic and I as a young adult for no real reason was extremely fearful of becoming like him.... a schitzophrenic. I started treatment after I was 11 because anxiety was keeping me from interacting. Although I do believe this had to do with the fact that I basically always obsessed about nonsence. At the time it was extremely important to me. It was like my "precious"
sometimes the things that I thought held so much power over me that, I would let the random non-sensible thoughts run my life. the Nonsene was what I should wear, what ppl would say at school to me, if I would have a snappy comeback to retort with, wether or not I would sweat in class, Homework, ect. , ect. So Ultimately I had all these things to worry about because when I worry and keep my mind busy it keeps me occupied ie. less anxious. Although after so long it builds up way more worry than you start with, so yes I too started to become parinoid I was probably 7 or 8. I would obsess that grizzlies in my grandma's woods were stalking me from the trees. Not totally unfounded by the fact that my grandma told me there were grizzlies out there so that I wouldn't play in the woods. But I digress, After I started
taking adderall I became very "aware" that things and or ppl were watching me. Also I'd like to say giving an OCD person adderall is just ludicrious.

I ended up hospitalized.
My point is that I for alot of years built up kind of an imaginary world. The real one was just too harsh.
I know thats totally a cop out because if I never had real things to worry about I probably would have worried anyway.
Also talk to a phsychiatrist they will give you alot lot of answers you just can't be afraid to ask... I mean anything .. it is by law totally
confidential unless your involved in a crime.
Thearapy helps but when your afraid of things that you or anybody else can explain ...and I mean explain. You can't beat a good Phsychiatrist.
Right now I'm diagnosed Schitzo- effective. I have only just really realized I'm so obsessive about things. I actually thought that part wasn't an issue ....

my bad right.
So I take Klonopin and that slows the thought processed way down for me. To where I can go outside and not worry about ppl looking at me. Well if they are looking at me I'm not so concerned about it ...
Good luck my friend its a loud, and shiny world we live in...Hope for a day that we can all just enjoy it.
