Is ocd a disability? and could i have it but with thinking?

well when i first when into the hopital after the first couple of days after valentines day, after having a panic attack,they told me that i was diagnosed with GAD. General Anxiety Disorder but i feel that it's so bad now it might not just be anxiety. i believe that it could be ocd. obsessive compulsive disorder but with thinking. there are a lot of things that i did when i was younger that i would not have noticed until a friend of mine said something to me about a week ago. she said by the way i'm describing my situation to her, it could be obessesive compulsive thinking. when i was younger i used to get up in the middle of the night and i thought something was wrong with me because i had to do something, i had to write or something to alleviate this strain of anxiety. i was afraid of growing up and constantly thought about the people around me dying or me moving or losing my friends, and it's sad because some of the stuff i thought about came true but years later. and now everything is starting to come together. i'm very finnicky about a lot of things too that i thought were normal that might be described as ocd. like i write about everything but i feel the need to doent it and save it for some reason. i'm a mental hoarder, like i try to hold a lot of things in my mind and that's probably y i'm stressed out. so technically i had this problem since i was a kid but since i never thought about it being a problem, it wasn't one and since i never really spoke to anyone about it, it wasn't exacerbated like a problem. so what do you think of my new ysis? seriously though. i think i might have that and i'm not saying that because of the anxiety, i think the anxiety was supposed to happen so i could discover what i had all along.. maybe.. what do you think?
