Thats because its a long, arduous process that cost me over $10,000 to make sure my case was airtight, removing ALL liability from the FAA. Most people either 1. don't report it and continue flying, 2. do report, get deferred, and get off the SSRI or 3. Do what I did, focused on my health and found a great SSRI that works wonders for my seritonin deficiency.
Option 3 requires up to 2 years of wait time, a lot of money, and a lot of patience that most people aren't willing to deal with, if they have a choice. I just decided it was worthwhile to take a break from flying and focus on it.
Since I've been so thorough, I think I have a really, really good shot. Hopefully, it doesn't take a year for them to review.
