AM ON ESA IF I FAIL PIP WILL IT AFFECT ESA?

Hi there - am on ESA SUPPORT GROUP- have never applied for pip as im too terrified. i got told my esa review has been given 'dispensation' for 2 years now review due may 2020. i last completed review form 2014. NOW HAD APPOINTMENT WITH MENTAL HEALTH C.A.B. to ENQUIRE bout if id qulaify for pip as i am struggling financially - for DEPRESSION EXHUASTION PTSD - cant cook meals on cooker only go out 1 or 2 days a week dont bath 5 days week etc - she said she could def get me pip- & rang dwp straight away ! got form muchharder than she said. .MY QUESTIONS _A_IF I FAIL PIP ASESSMENT- WILL/COULD IT AFFECT MY CURRANT ESA SUPPORT GROUP STANDING /COULD THEY BRING MY MAY 2020 REVIIEW FORWARD OR COULD I LOOSE IT ALTOGETHER? B-C.A.B LADY TOLD ME THEYD SEND FORM FOR ME TO GIVE TO GP TO FILL OUT BUT THERE IS NO FORM IN PACK. it says not to contct gp. i have old support letter. I AM FINDING WRITING NOTES TO FILL OUT QUESTIONS EXHUSTING AND MAKING ME ILL- IF I HAVE TO HAVE FACE TO FACE ASSESSMENT I HAVE NOONE TO GO WITH/NO SUPPORT. MAIN QUESTION- UNDER NO CIRCUNSTNCES DO I WANT TO ENDANGER MY ESA WHICH IS SAFE TILL MAY 2020. I DONT KNOW IF APPLYIING FOR PIP IS WORTH THE STRESS AND RISK. CAN YOU ADVISE ON IF I FAIL PIP WILL IT AFFECT MT ESA IN ANAY WAY. PLUS when i filled out my last ESA FORM IN 2014 I WAS VOLUNTEERING 1 afternnon a week for the police- my health has deteriorated considerably so i stopped volunteerig and going out as much. WILL THE PIP PEOPLE LOOK AT MY LAST ESA REVIEW FORM AND SUPPORTING EVEDENCE AS PART OF MY PIP ASSESSMENT ? AS MY HEALTH IS A LOT WORSE NOW. as my health is mainly meantal health but it TOTALLY AFFECTS MY DAILY LIFE COZ OF EXHUSTION /UNEABLE TO COOK BATH ETC it seems very HARD TO PROOVE. I AM IN SUCH A STATE IM THINKING OF CANCELLING THE PIP APP. I HAVNT SENT FORM OR HAD 2ND APPOINTMENT WITHCAB YET SHE HASNT RETRUNED MY CALL AND I HAVE NOT BEEN REFERED BACK TO MENTAL HEALTHTEAM AS PAROMISED BY HER. AM V WORRIED.. ANY ADVICE APPRECAITED. THANKYOU. ( sorry so long)!
