Going unmedicated?

My boyfriend of 7 months has bipolar (not sure which type), ADHD, anxiety, and PTSD, and is supposed to take a mood stabilizer in the morning and a night time medicine to help him fall asleep as well as help void him having any dreams. About a month ago, he ran out of his mood stabilizers and he mentioned to me that he’d set up an appointment soon because he was gonna start working soon. But he ended up starting work before he anticipated and now hasn’t set up an appointment. So he’s been without any sort of mood stabilizers for a month and I can tell it’s really affecting him. He’s generally an emotional person (he’s been through a lot and just cares a lot about things) so it’s not abnormal for him to become upset easier than most, but I noticed he gets EXTREMELY upset over little things to the point where he’ll break down and tell me he notices his depression worsening, that it’s hard for him to want to wake up, that stuff really bothers him, etc. I keep telling him that he needs to set up an appointment but he says he wants to switch therapists first bc he doesn’t like his current one. But he’s been saying the same thing since June. And he’s concerned about taking time off work. I’m so worried he’s gonna go off the deep end before he can manage to switch therapists and get himself into an appointment. idk what to do anymore bc I’ve tried talking to him but he always just says he doesn’t wanna miss work and needs to switch therapists
