Is it a bad idea to ask my psychiatrist to take me off my meds? Specifically the Thorazine? I'm really conflicted about it. I want to lose weight and it's hard with the thorazine and I sleep a lot/sedated a lot. I don't want to replace it with anything, just come off of it

Also my bf doesn't believe I have any mental health issues even though I do, and that meds aren't great but said he won't tell me what to do as far as whether to come off them or not
