Hi, from what you've said here, it definitely sounds like you have mood regulation issues. It could very well be BPD or Bipolar 2 or both (doc says BP2, I say BPD). I have both, and I can relate to all those issues you mentioned.

I'm sorry to hear that your mom is being so unsupportive esp with paying your medical bills. Have you tried explaining it to her in detail ? Are you unable to support yourself ? Do you go to school ?
