Hi! I had my medical just last week. I have a history of depression and was on medication for 4 years, but came off it several months ago.
My doctor was useless at giving me detail on it: my patients summary just said “Depression Resolved” on the date I started coming off my medication. Didn’t even have a start date for it.
The Visa Medicals doctor asked me some basic questions about the condition and ensured that I was now feeling fine. I specifically asked and the doctor said she had no concerns.I think your letter sounds like more than enough.
Best of luck!!
