Hey Molly,
Maybe it's just me but I think there's something a bit wrong with the help you've received so far. (No one should have to wait that long or be given only three sessions, in my opinion)
Did the doctor say how long you'll be seeing the new counsellor for after the wait?
No pressure to answer, it makes me rather grrr though hearing of others who suffer as I have done because of the inadequacies of the NHS. I don't have a social worker either but have received better help when I don't let them "forget" me. It's easy to feel that way, for sure, and to feel undeserving because of the way some of the staff may treat us. Thinking of you
