The nurse practitioner I'm seeing about my ADHD diagnosed me with bipolar disorder

She literally could not have surprised me more if she tried

This makes no sense to me but it's scaring me a lot :(

I don't really remember having manic episodes? Depressive maybe but it's usually after something bad happens to me and not really consistently....

I told her I put off making this appointment cuz I've been feeling really bad recently, then she just asked me a few questions like if people say I talk too much sometimes or if I do things impulsively and prescribed me an antipsychotic (aripiprazole) wtf

I asked some family and they haven't noticed anything like this... idk :(. Has this happened to anyone else? Am I just in denial? I'm afraid to take this drug she gave cuz I really don't need to be even more tired all the time... or tardive dyskinesia or something (unlikely, worst case)
