I would start thinking now about which attorney you want to represent you. They usually offer a free consultation. It would be good to get their opinion about whether the at-home work you're doing now (assuming it's "over-the-table" and taxed) will affect your efforts to be approved for disability benefits. They can probably also tell you about how long it's taking in your area for cases to come up before a judge for a hearing.

There are two approval/denial stages before the judge hearing.

You sound like you're mentally prepared for the process and it's great that you've already done your application.

It's good that you're eligible for SSDI because it gives you much more flexibility to do work trials in the future.

Best of luck to you.
