I hope you are safe. I've never called a suicide hotline, but it may be an option if your T isn't taking you seriously.

I've experienced the exact same thing - I tell him I'm thinking about it all the time, and he does nothing. The only time he has was when I was drinking and crying to him on the phone about how it would be best for my family if I'm gone. Then he scheduled me to come in the next day. Looking back, I probably should have been in the hospital at that point. He's a psychologist and I need to just trust that he understands what's going on most of the time, but I still feel neglected when he doesn't take my suicidal thoughts seriously.
