I don't know how old you are, but honestly, you have a right to question your diagnosis. If you're old enough now, you can find a new pdoc and exclude your mother from the sessions. As an adult you have to sign a release (at least in the US) before they are allowed to talk to anyone about your case. If you refuse to sign one for your mom they can't talk to her and she can't throw her two cents in. As an adult I have been asked if I wanted to include my mother but I have declined. I have also declined to include my husband at times. No one can force you to do that. That way you can give your history as YOU see it and let the doc decide what it all means.

Honestly what I've found is that as a teenager you're assumed to be a liar who doesn't know how they feel. I clearly remember my many hospitalizations and the fact that they always believed my mom over me. Once thy said they wanted me to go to residential because I wouldn't follow my mom's rules if I went home....hilarious because she HAD no rules, literally, but had pretended she did and I broke them To make herself look better

Btw you can tell your mom that mania is RARELY diagnosed in children. Bipolar generally doesn't come on till teens or later. I highly doubt you were "manic" as a child.

Seriously, question question question. It's the only way you can be sure of anything.
