Thank you for asking this question. I understand how overwhelming it must be for you to experience this.
I would suggest you to understand the triggers and understand what is causing the bad mood and sudden outbursts. Talking to a friend, journaling what you feel, meditation might be a few ways to deal with it.
However, this might be hard to deal with, if it gets overwhelming, please consult a therapist.
