Hi Annette
I am sure that everyone on the site appreciates your worries and concerns.
There' not muchcto be done to help, other than to say that if you use the guides as they are intended to be used you will give yourself the very best chance of success with PIP.
Download and read carefully the descriptors, decide which descriptors best fit you and your illnesses and circumstances and use the guidelines to fill in. your application. Gather all the supportive evidence you can from doctor, consultant, carer, family, friends, anyone who knows how you are and how you manage (or don't manage) with your health issues. Whatever you do, please DO NOT just tick boxes - explain fully!!
Send it along, recorded delivery/special delivery and KEEP a copy for yourself, so you can remember what you wrote. Then wait and keep your fingers crossed.
Good luck
