Is it normal to not feel the same after a panic attack?

I had my panic attack 3 months ago and since then everything has snowballed out of control, i spent so many hours looking for assurance but one thing led to another and now i don't know whats wrong, i haven't had a panic attack since then but i can't shake the feeling of uneasy. I read about schizophrenia and ocd, and now i feel like im having the symptoms. Sometimes i wish i could go back and stop myself from learning about anxiety and everything else. I have become so much more aware of everything around me, my thoughts are out of control. Last month, i developed intrusive thoughts and concluded that i have OCD afterwards i started thinking about the thoughts and wandered if maybe i'm losing my mind, thats when schzophrenia came into the picture. I just don't know...i'm confused but at the same time i know i'm still me and I'm normal. But still...i can't shake the feeling of uneasiness.
