As I recall (it's been quite a while), there really wasn't a huge amount of "work" for my Drs to do.
Just ask if they think you are capable of continuing to work, immediately after telling them how your current symptoms impede your work. When they agree that you can't work, that tells you all you need to know, ie. that they support you in not working. The rest of it is in the form of record requests directly to the Dr from SSD, which they cannot refuse to co-operate with. There really is NOT a huge burden put on them that would influence their opinion in a way that would keep them from supporting your disability.
I didn't use a company and I didn't find it particularly burdensome to fill out the required paperwork for SSD. (To be fair, I owned my own company and had for many years, so anything about
my work experience and earnings I filled out from the standpoint of both employer and employee.)
I feel like you are making it a lot more difficult than it really is, it really isn't that bad, I promise!
