Struggling with BPD after a Breakup

I’ve been slowly losing the will to live over the past week. My fiancé and I broke up a week ago, I have BPD and they’re my favorite person. We’re still roommates and friends which is good to an extent bc I know I’d be dead if I had to move away from them. But I don’t wanna be attached to them like this, idk how to make it stop it’s driving me insane. I’m watching them get over me while I’m stuck. I need to go inpatient, I know I’m not gonna be able to keep myself safe much longer. But if I go inpatient I won’t be allowed to live with my fiancé’s family anymore, I’d be homeless. Plus I have work in 30 minutes, I stayed up all night and haven’t had my meds in two days so I’m going through withdrawals. I don’t know what to do about anything.
