PIP medical

I am sorry for previous post. I have now had help with this email
I have severe mental health problems and I will soon need to apply for PIP. I was put in the ESA support group without a medical within 6 weeks due to the supporting medical evidence.
My CPN and my psychiatrist are providing a joint detailed letter for PIP and are saying again that a medical would be likely to cause relapse and would be too distressing for me. I am not able to answer questions and would feel very threatened which would make me aggressive. It would not make any difference where it was held or if I had someone with me - I can't do it.
Do you think I mazy be able to have a paper assessment?
Should I also send the ESA information?
Thanks
