I had a VA diagnosis of GAD in 2014, completed psychotherapy, and had no issues since therapy concerning anxiety. I was prescribed an SSRI that I didn't take during that time. Here is what happened concerning my medical clearance after my analyst received my active VA, then eventually my active duty records:
1. Spent $700 on a functional capacity evaluation for my disability claim concerning my knee
2. Spent $1400 many months later on a psychiatric/psychological evaluation for my previous GAD diagnosis. In this eval: I did another MMPI2 (despite not having issues with the first one), a trail making test, several questionnaires, a long interview, and the WAIS-IV.

I was from the 2018 bid, and my total wait time was around 570-something days. Everything sped up once the wizard checked me out.
Hopefully your process is better. 10/10 would not claim GAD, and if you've got this in your records they likely will see it and pick it apart.
