Mental health has deteriorated whilst waiting for esa assessment

I sent Uc50 form in mid Nov 2021, I have heard nothing yet. I agreed to have help from Shaw Trust via jobcentre, however my mental health has worsened to point I have rang samaritans twice in last week. I also rang jobcentre to let them know that my condition has worsened and I have been feeling suicidal, when he said to me sarcastically 'is it because of your work commitments' I said u have to be f***ing kidding me and he said because you have sworn at me Im putting the phone down. The only work commitment I have is to be in touch with shaw trust. They find it difficult to help as because of the severe sexual abuse I had in chdhood I need specialised therapy which they can't provide. I have had 2 bad advisors there that have affected my mental health so they put me back to someone who understands me, however my point is I feel like I've had a breakdown, I know I should be in the support group. I was in Support group back in 2011 for 5 years after a major breakdown and under the care of. Psychiatrist. Please can you advise what I should do.
