How to tell new bf about my mental issues

I had a big ol' mental breakdown today. Just quit a job on the first day. Had to visit one of those crisis mental health clinic things. The good news is I now have a therapy appointment set up for next week. The bad news is I am now unemployed and fucking up my life again.

And I just started dating this wonderful man of my dreams. We just started dating a week ago. He knows I'm bipolar but that's it. He's never witnessed anything "weird" or "bipolarish" about me. How the hell am I supposed to dump all this on him without scaring him away? I'm supposed to see him tomorrow and I don't know whether I should fake it and act like all is well or what. I hate this bipolar shit.
