Help! I have to pack up and leave ex-fiance this afternoon. He wants me out tomorrow?

He broke up w/me 4 mos. ago b/c he doesn't think we are compatible nor does he think he can make me happy. He was nice enough to let me stay in our aprtmt. we had together for last few months to get my act together- to find a job, etc. I'm unemployed still, but thank God collecting long term disability for now while I work on myself. I didn't have the courage enough to leave situation any earlier. Tomorrow is my ex's deadline for me to be out & I'm miserable about it. I've been suffering from major depression for many yrs (do have someone I see for counseling and anti-depressants.) I'm having a really hard time accepting fact that I may never be able to see my ex or talk w/ him again. I'm still in love w/ him & can't let it go. We were together for 4 yrs & can't face not having him in my life. He's a good person. I'm going to have a REAL meltdown. I feel awful re: moving in with a friend who only has 1 bdrm apt. I'll be sleeping on her couch; she smokes; no storage. God help me.
