can't say that i envy you! this can be a long and frustrating road, but once you're approved, it's okay.
went on ssi before i was dx w/ms. was recommended tyhat i apply by psych i was seeing. had to see gov't. doctor and was assigned a case worker or something like that. more like an invisible unfeeling individual who was of no help to me at the time. had a friend living nearby who worked at a private psych hospital who helped me w/paperwork. also had other friends who made phone calls for me. this was all about 8 years ago.
do keep copies of everything. the beauracracy is good at misplacing or ignoring written communications. also kept written notes of phone conversations.
took a year and 1/2 to finally get approved. by then i was on welfare, foodstamps and medicaid. still used up all my savings and was bailed out for rent by friends and church. you get all the benefits due you once you're approved, but then foodstamps, etc. end.
while going through it all, just wanted to give up. government can make you forget that it is your money you're asking for. wish it was easy for me now to say "keep after them" but it is a most demeaning experience. i was approved without appeals, so was easier for me. hear that many individuals have to reapply, etc. if i had had to wait longer and face more beauracrats, don't know where i'd be. all i can tell you is that once it's over, it's over for a few years. good advice to contact ms group. best wishes and luck in your road ahead. linda
