Oh, I'm so sorry this happened!

While I am not dealing with so many very big issues as you are, I recently had the same T experience of feeling like it was a time I needed T the most, but it didn't happen and worse, I felt totally unheard and unseen. We are working through it now but the one session where I waited and waited for it to come, holding off on melting down for 2 days as I counted the days to get to T, and where I sat in tears and said about my issue, "I can't DO this!" she was moving on to how I was going to be able to do 'this'. As if rushing past my feelings, as if I wasn't sitting there in despair and stating explicitly why. One thing she said was that she felt a desire to 'fix' and that is what made her talk about how 'this' could be done.
So, ironically I had a need and desire to be rescued and she felt a desire to rescue but it bombed the way she went about it, or I don't know how to recognize it, or whatever.

It just feels so awful to really want and need to be seen and heard and relieved, but for whatever reason it just doesn't feel like that is happening.
I hope you will talk about this next time. Can you call your T to talk briefly before your next session? It might be relieving to let her know how you feel and that you want to talk about it next time.
