Congratulations on being awarded disability!
I vaguely recall being told the same thing when my disability was approved, 4 years or so ago. I worried as well. One thing I've discovered since then is that I have to fill out paperwork for SSI, county assistance, and my apartment quite often. Like every 6 months - 1 year. I don't like it, but I do get assistance to help me through answering the Q's. (I become easily confused, especially when I feel stressed out.)
So far, I haven't heard anything from SS questioning my disabilities, so maybe that happens behind the scenes.

Try not to worry. Focus on what you need to do to get yourself into a healthier state of mind and body. Best wishes and gentle hugs to you!
