I’m sorry you’re having such a hard time. I would tell your pdoc about everything - hurting yourself, your parents, stopping your meds.
You’ve been back on your meds for a week but that isn’t enough to bring blood levels back to therapeutic so you may need something like a prn to tide you over.
PRN Quetipine 25mg is sedating at that dose. I take a low dose at 8pm every night to help me sleep. Given that you’re already on it, is there anything to stop you taking that as a sedative?
