It’s hard and I understand it because you can overthink all this and it’s quite common. We’ve all been there and there’s reasons why the doctors say things. Sz is a serious disorder but untreated sz really isn’t very good and most likely brain damage. Even depressive episodes are probably damaging the brain too.
It’s not so much about the diagnosis anyway. It’s about the results of treatment. If the medications are keeping you out of trouble then it’s a good thing. You need them. If you don’t need them or they cause problems you’ll soon find out. Most of us here go through changes in diagnosis.
So. No. You shouldn’t but I realize your new to all this. Best advice. Don’t overthink it and just do what you need to do. Concentrate on study or whatever you are doing and try not to obsess about sz or the label. That will look after itself.
