My experience, if nothing has changed with the diagnosis and you haven't been able to work, you should be fine. The reviews are just part of tfhe process. They need to be sure you still qualify, that's all.
I had a review after I had worked for a year and a half, but had just recently quit due to my disability. My review was still approved, even tho I had been working. Social security was aware of my working and I only went over my allowed income once, which I had to pay back that month of SSDI, which was difficult but manageable since they allowed monthly deductions from my check.
I've been on SSDI since 2003, and have had reviews every 3 years. I've worked on and off, trying to see if I can, and I've never been able to keep working after awhile. Every review I've had was approved.
