b12 supplements and med reactions

I am not asking for medical advice.

Hello, so I guess what I am asking is just if my theory is correct.

I have borderline personality disorder and am on multiple medications for such, like rexulti, viibryd, trileptal and buspar. I started taking 1000 mcg of b12 daily at my doctors recommendation and it has literally ruined me. my medicines have completely stopped working and i feel like i am withdrawing from them, having brain zaps BADLY and dizziness. My theory is i do have the gene mutation (?) that makes me react to b12 with anxiety, depression and psychosis symptoms (which for me all go hand in hand and create a literal monster of a human), and through that, it’s mimicking withdrawal symptoms, or that the b12 supplement is just causing both. The brain zaps have been mostly at night when laying down, but probably every 5 minutes and they’re causing false awakening dream loops and sleep paralysis. and they’re STRONG. a nurse practitioner thought it was low b12 and gave me a b12 shot when my blood work showed my b12 as “low side of normal”. This is just what i can gather. From what i can term i can also take another form of b12? like made a different way? is that true?

TL:DR: Is someone in agreement with me that my B12 supplement is causing psychosis like symptoms and severe brain zaps, and will stopping b12 help?
