I don't necessarily see any unprofessionalism in your description. You describe your feelings which are perfectly valid. You also mention some things the therapist has said, which, when taken out of context, can be interpreted which ever way one wants them to interpret (most probably incorrectly though). It's possible that you are not a good match with this T though.

Could you explain what do you think/feel in particular was unprofessional regarding your T? I mean that you feeling abandoned definitely isn't a sign of therapist's unprofessionalism. It's a symptom that no therapist can take away from you unless you work through it somehow. The exception is of course when the therapist clearly acts in an abandoning way, which I don't read out from your description.
