I am constantly fearful that my therapist will leave me, that it's practically debilitating. For the last couple of years, I have had a very acute fear of abandonment, which was exacerbated last year when I had two therapists leave (one because he finished his residency, another because he got a promotion, both legitimate reasons). I've been with this therapist since December, but all I can do is think about him leaving me. 

And I necessarily wouldn't blame him. Out of fear, I sometimes email him, sometimes multiple times, before our weekly meetings. Sometimes, the message isn't completely sound of mind. I always end up apologizing during our meeting. He doesn't make me feel bad about it really, but reminds me that he won't always answer me because he wants me to work out the emotions myself.

I still feel incredibly guilty though. And what's worse, I'm very sensitive to any cue that he might be leaving. For example, during our last session, he mentioned in passing that he was crunching numbers the night before and worried that rent for his practice was rising but insurance payouts aren't. So now, I'm afraid he will leave his practice in favor of a higher paying gig, which I can't blame him for. I expressed my fear afterwards, and he reassured me that wasn't the case. But I'm still very fearful.

Any advice for this incessant fear?
