Disability Lawyers: Attorneys for SSI and Disability Claims | DisabilityLawyers.com and check around in your local.
I had lawyer as backup if there are problem with SS. It took 3 months for me to got approved for SSDI because I have more disabilities than just deafness only, that's met the strict definition and got approved without went through the court. I found those process is extremely red tape and you have to submit a lot of medical statement, also they will contact your former employer for questions.
If you had SSI before and you can to get reinstated, so continue until you get approved for SSDI or find a job that meet your needs.
I'm sorry that you don't like previous jobs, but I know many people don't like job, especially low paying, minimum wage jobs.
