pip review forms

hi all ,i have been putting off filling in my review forms as i dont know where to start.i have mental health issues and my forms need to be in by 28/8.if i telephone them to request more time will they hold it against me the fact i can use the telephone/ fill in the forms myself?this is because i have no family to help me and i am reluctant to seek help from cab/age concern etc as i suffer with really bad social phobia so i have no choice but to fill in the forms myself witch im sure i will make a complete mess of.will they hold it against me the fact i can make the phone call and atempt to fill out the forms?this is making me really ill and i dont know where to turn.many thanks in advance connor
