Will PIP affect ESA claim? very hard PIP interview

I just had a PIP interview today, and it was much more intrusive than I was expecting and I'm very worried about how it might affect my ESA. I just appealed an ESA decision earlier this year with 20,000 words plus mandatory reconsideration. I was granted ESA on sections 29 and 35. The letter I received also said "to be re-referred 2018". I'm on the support group.

My issues are around social anxiety, general anxiety, depression, addiction and a variety of challenging mental health symptoms. I have been trying hard for a long time to get into a place where I can work and live life again, and I'm nearly there, but I am currently recovering from addiction now and only 4 months out of an accidental overdose. I'm very committed at this point to staying clean and getting better.

I tried to claim PIP as I thought it would be a little extra money to help with therapy, which I get once a week privately (my parents lend me the money and it's adding up).

I didn't realise the PIP questions were so extensive, and the appeal process I went through for ESA was extremely difficult for me so I have left today extremely worried. I feel that I answered some questions differently to in the past, and also due to the fact I am trying to do more in the real world and challenge myself to get out to support groups and therapies in order to get better, that this is evidence that I am "fit for work".

I was asked things like "when did you last work" and other questions that didn't seem related to PIP. I have had "market research companies" call me before to ask me about work after Uni, and when I searched the phone number they were a private firm that's contracted by the DWP. It's all very paranoia inducing. I have worked on a recovery plan for so long and the idea that this effort to get some extra support might backfire and affect the 2018 referral date is very worrying. Today I nearly snapped, so I hope you don't mind my rambling.

Lastly I have been trying to get a full diagnosis through the NHS but they referred me to drug centres. I am clean now and I have been to those centres in the past so there is nothing there for me. My therapist has pushed me to get a full diagnosis, to rule out autism, and to lay out all the symptoms I have had in the past that I haven't talked about with a psychiatrist. There is a psychiatrist who I was seeing, but he was very patronising and never really gave me a proper diagnosis nor had complete information from me and he didn't support my appeal as he just kept going back to drugs and not mental health. So I am waiting for more clean time in order to follow up with another psych once I have stabilised, or to push the NHS for support again.

I worry that ATOS would call the old psychiatrist and he would not support me, or that I have not had a full diagnosis recently (but I talked about getting one extensively in my 20,000 word appeal), that might also count against me.

Best wishes

Just read your last sentence. Pip decisions taking 204 weeks. Good grief.
