From DLA to PIP

Hi everyone, regarding PIP I've received my claim pack to go from life award high on both to be transferred over, filled all of that in as per your invaluable notes, then I received a date for an interview which they came to my home now after about 2 more months have passed I thought great the dreaded brown envelope has come but no it's a letter saying they have all information and they will be making a decision soon, how much longer could it take. I enclosed all my consultant letters regarding COPD, Wegners granulomastosis, Autoimmune Neutropenia, Osteoarthritis, Osteoporosis, degeneration and major damage to both knees and hip but cannot have replacement because of other problems so I struggle daily with getting about and medication of morphine. I would have thought with all the information that it's obvious that I'm just going to get worse as each year goes by but no they want to torment mentally and cause so much worry and sleepless nights. Has anybody got any idea how much longer you have to wait for a decision. Things I've read I'm not holding my breath and I'm expecting to have to appeal but we'll see.
