Hi, welcome to PC!

I can mention that it could be, but I’m not a professional so you could look into and talk to a mental health professional after, borderline personality disorder. Mood changes tend to be quite rapid there, with doing impulsive things like the things you’ve mentioned with the note and such. But you most likely will not be diagnosed with borderline personality disorder because it is considered an adult disorder, meaning that only adults are generally diagnosed with personality disorders due to the changing personalities of teenagers.

With the anger thing, it could be what I mentioned also, but I have found myself quite angry the past week or so. Minor things have been setting me off (clenching, swearing/holding back). I have never been really angry at all. I was told that I must have a problem because I never got angry. Like at all. But now I am angry. I’m unsure if it related my depressive episode or if it’s related to all the things regarding the episode, like meds and therapy and waiting.

Are you seeing a psychiatrist by any chance? This may help with your mood. It’s always good to get help. I know you are already seeing a therapist, but getting an opinion from a psychiatrist may be helpful too.

I hope you feel better soon.
