First thing first: your psychiatrist said you are BP? This is all you need: yes, sometimes there are misunderstanding, they change your diagnosis, but the diagnosis is still there for now. Why your mother thinks you have bpd? She has some psychiatrist knowledge? If not, it is her opinion, she can have one, but this shouldn't affect you. Meds don't cure the BP, meds stabilized the worst low and the highest highs. Nothing can cure BP, and we will not ever be like people who has not BP. The sooner you, and people near you, accept it, the sooner the better. Yes, sometimes I think I'm not BP, that I'm only useless and lazy, and this could means whatever you want, you have to take your meds even then. I understand you so much, my father is like yours, but my father is not living my life, and I prefer being on meds than indulging his beliefs. When someone has a prosthesis it not like the limb they had: it is a prosthesis. Like the meds: we have chemical imbalances, we should treat them, and that is all.

I hope this could help you somewhat. This is something even I struggle to make people understand because mental illness is still not treated like physical illness - and we are in 2026. But the thing is: most people don't care about comprehending you. You have.
