Just on meds , especially APs , those drugs are largely there to stop specific symptoms , hallucinations especially , you still got to do all that positive stuff to keep your mood in order.

For example if a healthy person , non sz , started to think and do stuff that was not a bit positive , then they too would end up depressed and anxious , its just the way our brains work.

The problem with APs is that they can make people feel a bit off as a result of them so that can add to the problems , the trick is to use them with a specific goal in mind , I.e to stop hallucinations , then to quantify their negative effects , by saying this is the price I pay , and then after that to do all the positive stuff so as to maintain your mood , (just like everyone else does)....
