I'm so sorry you are in that situation. It is very similar to one I was in before, so my heart goes out to you. Wish I knew what to say to help. I usually prioritize my mental health over other concerns but sometimes feel bad about it.

A psychiatrist taught me a technique for dealing with uncomfortable social situations although it is a bit over the top. He suggested I use my imagination as a tool. His advice was to imagine that I was from another planet here on the earth to observe human behavior. I would go into unwelcome social situations with the ulterior motive of collecting data on human behavior. He said that this would take the pressure off of me to be a certain way around others. I tried it a couple of times and it got me through some rough spots, socially speaking. Not suggesting that this is something that would be helpful to you or others, just sharing what helped me.

I hope you will be okay whatever you finally decide to do.
