Lost

I'm kind of at a loss of what do to with the news about the practice. Because of my feelings about my job I've been looking for a while now. Here's the thing though... when is it gonna sell? I really don't want to leave him hanging, but it's been on the market for over a year already. I really don't want to hang around for another year. It has my emotions very mixed. I have some real opportunities to jump at, but what if I get the job and he hasn't sold the practice yet? I don't know what to do. AAAAAAAAAAHHHHHHHHHHH!!!!!!!!!!!!!!! Tension breaker had to be done. I can't afford to put things on hold, and yet how far forward do I move? I know that I need to look out for myself (selfpreservingly), but I don't want to hurt him while I do this.
I am a real pro at driving myself crazy. Someone tell me what to do. Please.
