Yeah I don't know anybody you has actually gotten SSi in six months personally so I doubt I will and I know about the back pay but that doesn't really matter right now as I am totally incapable of paying bills and eating. XD
I do have severe depression, anxiety, and PTSD but never had money or doctors in FL so I still have to see doctors to get diagnosed for that and I can only handle the appointments for my bladder at the moment. I can barely leave my home and pee like 60 times a day and can hardly afford to miss days of "working" on mturk just to get to all the appts I have for my bladder. So, it'll probably be at least a year for me and I don't know how I will make it.
Yes, the "right now" is the hardest part. Perhaps you could get some food assistance and help with the primary bills like rent. There should be state programs for that kind of help, but I don't know what's involved with getting that kind of assistance where you're living.
