It's been 2 1/2 years since my first psychotic break. I used to ruminate A LOT about before and after the break: how I felt, how confident I was, how sociable I was, and so on. Truth is I never felt "normal" after the break, but I began to learn to deal with it, and it takes time.
Today, it's been almost 3 months since my second break (both drug-stress related), and I feel ALMOST the same way I felt after the first episode. I think I know how you feel, man. I relate to a lot of the things you describe. Booze doesn't hit me, conversations seem fast-paced, I sometimes think that people will "notice" what happened to me, but I've come to realise two things: (1) No matter how hard you ruminate about the former you, all you have now is your present, (2) as long as you keep yourself busy with stuff (work, books, close friends and family that won't judge you) you will start feeling better.
I know it's a hard path, and no one would ever choose to have a psychotic break and have to walk it, but the only fact is that we're here now. It's up to us what we do with what we have.
Cheers.
