Kiya,

It sounds like a scary situation.
Last week after bedtime my son came to me because he was scared.....of a lot of things. I couldn't fix it for him, I couldn't take away his fears. But I could give him a hug, let him know I was there and that I was sure everything would be ok.
No, your T and other support people can't fix it, but they can be there for you and show their concern, their support and their caring for you, and remind your that there are other things you can do (like the ER) instead of harming yourself.
They can be there so maybe you don't feel so alone with your fears.
Please reach out to them! You are not alone!
I hope you feel better soon.
