I empathize with how you feel. I've been through pregnancy of one therapist, and the death of another, feeling major abandonment each time.

I would just encourages you or anyone to realize that we can't control what happens in another's life. When my last therapist said she would not abandon me I knew she meant it, but she also taught me that there are situations and decisions that are not static with time: death, illness, kids needs, moving — change of plans. IMHO.

I hope you find find some peace to get through.
