SSI (SS Income) and SSDI (SS Disability Income) are not the same, and SSDI is what you are seeking. I had SSDI for about three years until reaching 65, then was automatically switched to SSI since 65 is apparently the end of one's expected working years. Getting SSDI will likely be difficult or even impossible if you are able to work, and having an attorney is typically for making an appeal after having been denied. I was able to get "Food Stamps" and some other local assistance while having no income prior to SSDI, and I think there is where Medicaid can play a part. As far as I know, there is no cookie-cutter process for jumping through all the hoops on the way to hopefully receiving SSDI, and my own case was ultimately decided in my favor by a substitute judge after the attorney handling my appeal had told me I had no chance of being approved by the judge he had thought would be deciding my case. Overall, and with the help of any doctor or doctors who might be willing, it is up to you to prove you cannot work to support yourself. Also, SSDI amounts are based upon past earnings rather than being the same for everyone.
