I think it could be a good idea, at your next session, to say the things you have written above to T: you feel you are unwell and getting worse, you feel you aren't getting enough support, and last time you shared this you feel T didn't do anything. You could ask what is T able to do to support you, and what is the plan going forward.

I think it will be a good idea not to accompany this discussion with mentioning SH, because of what you mentioned above- that T will be wary of responding directly to that kind of communication.

My T did not really discuss SH behaviour as such with me. He did remark that it doesn't solve any of my problems and it makes me feel bad about myself, and that's what he thinks is bad about it. We have more focussed on resolving the underlying problems, and then the need for SH went away as life got better, for me.

I hope you feel better soon.
