I hope you are feeling better now, even if it's just a little bit
What happened to you is pretty disgraceful, all I want to do is give you a hug! Something similar happened with my former therapist; the first few weeks I started seeing her, she was very open to me emailing her, and sounded/acted like she cared when I emailed her in crisis at one point. But then after about our 6th session, she started acting weirdly... I took a break from it for a while, then went back in early December. She wouldn't allow emails, and even if I did email her, she would reply with hardly anything or in a detached way. Then instead of talking about my problems like we had before, she started getting me to do worksheets. And I mean
a lot of worksheets - I had to take most of them home. Things changed drastically from there on - it was like she had completely detached herself from me and our appointments. Like she'd gone 'cold' and didn't care anymore like she used to...
I think it's safe to say going to therapy actually started hurting at that point rather than helping - I was anxious about every session, and over obsessed about it at the end. I dreaded going. I hated having to finish, because it hurt so much, but hey, that the NHS :/ But I think in the long run it will do me good
I hope things get better for you soon

Here for you anytime xx
