Hi Mandy,
Welcome to the forums. And, yes, it is comforting on here.
I just want to let you know that someone accepting you when you've not had it before can feel mighty weird. And because you haven't felt it before it is natural that it would feel unreal.
Maybe not everyone will act like your therapist, but a lot of ppl (specially here) will offer you the acceptance, space to talk, and understanding that has been missing from your life.
Well done for having the courage to be in therapy, and to start realising patterns in your life, and beginning to understand it all. It can be painful, but it sounds as if you are at that point where you can't ignore it any longer.
I wish you well, and please don't hesitate to post again. We will be here to catch you if you lose your hold.......
I hope you can get rest and hold onto something you love (your dog ?) and take one day at a time.

good to meet you............Poppet
