When filing for disability how did you come up with the date of onset for your disability. My neurologist is telling me to file for it. She is only treating me for "sleep disorders" mainly narcolepsy. I've had CFS since 2006, but don't see the doctor that diagnosed me with it anymore. Just not sure what to put and may have to get an attorney. I've talked to 2 different ones locally, but both of them said that I did not need to get them involved until I applied and was denied?!?!?!
