Here is a link I would recommend as worth checking out:

thedisabilitydigest.com

The founder of this site, or whatever you call the main person responsible, is named Brian Therrien.

It was from listening to videos and audios on this site that I figured out how to fill out the paperwork. I didn't buy anything from the site. I did buy a book at a bookstore.

That site receives revenue from advertising for lawyers. At the same time, there is no "hard sell" coming at you, if you subscribe to it. I would listen to audios offered by this website, while cleaning up around the house. Those were free. Little by little, I got to feeling like I understood much better what this process entailed.
