They can section you if they think you are a danger to yourself or others . This probably happens a lot less than it really should because of funding issues.

Have you not been helped at all? I remember you were with a T who changed their mind about what kind of therapy you should do. Did it not work out?

I'm sorry if nobody has helped you.

My feeling would be to try to talk to the T or nurse or whoever you have contact with, about how you are feeling, and see if they have anything to suggest. I'm sorry though if that is not helpful or if you've already tried that.
