Hi @Coffeelover
I experienced 2 psychotic episodes (three years apart), and I really know what you mean about feeling 'blurgh'... that is exactly the word for it! Both times, I would say I felt psychotic for about a week or ten days, then felt pretty flat and uninterested in life for about 3-4 months. It felt like my malaise was partly caused by the dulling effect of my medication (antipsychotic drugs) and partly caused by the shock of it all, and coming to terms with the fact that this had happened - so completely out of the blue.
I just kept trying to keep trudging on, going to work everyday, doing exercise and spending time with friends, until I started to feel better again. It took some perseverance. Changing medication also helped, and I wish I'd talked to my doctor earlier about how miserable I felt.
If you're finding yourself reliving the experience - perhaps it's worth writing it down, or drawing your interpretation of it, to give yourself some closure? If you're feeling ready enough to do that...
I've been well now for 7 years. Having a good therapist to talk to, as well as a good psychiatrist, is really important in my opinion.
