Sorry you have gone through this- I’m nearly at 5 months and I haven’t realised any clear recovery signs. I think you being in the ward right now could be advantageous, regardless of what everyone else thinks as you are at a point where you may need intervention to assist you. I don’t mean more antipsychotics, but maybe this PET scan you might get, may diagnose a problem with your dopamine receptors and you may get prescribed a pure dopamine agonist. Would you be open to try an antidepressant, if that’s a possibility? I know there are potential faults of taking them, but it may help lift you. I know if I was at 18 months and not recovered I’d be more open to trying things.
Anyway, I’m suffering myself and not giving advice- just a perspective. I think by you being in the psych ward right now is beneficial as you have a doctor who is actually listening to you. I suppose you could see if it’s an option if you could leave the facility and still see that doctor, but I don’t think that would happen. Anyway you have nothing to lose at the moment- do what’s required to get PET scan. It seems they won’t be prescribing you more antipsychotics, so you’re safe on that front. Best of luck
