Can PTSD make you feel like you're in a drunk "daze"?

It is depersonalization and it is caused by anxiety/panic. I had it for six years when I was battling panic attacks. I don't have it now, and don't have the panic either, so it is indeed something you can get past. But the dp is the worst and I understand where you are coming from. Dp is actually a state of hyperawareness. It is a place your brain 'goes to' when the amygdala has decided at any second you need to be aware of the predator you can fight or flee. It is a 'funky' feeling I know. I found that reducing my carbohydrate load drastically helped, as well as engaging in exercise that made me sweat. At first it would seem a lot worse, then it would kind of 'break through' and I would feel normal again. If you attack the problem knowing what it is and not fearing it, then you are more likely to get back to normal quickly.
