You will need a psych report before you can be issued with a class 1 medical cert. I have a similar issue. Had a class 2 re-issued 4 years ago but because I was under the doc and on meds (now just over a year ago) I need to go to Gatwick for a psych report in order to get my class 1. I've not flown since the event but in any case I need a doctor's report for re-issue of my class 2. Its very much on a case by case basis from what I've read but they are apparently very helpful. I'm starting my ATPL this year so going to need my class 1. How difficult that will be I don't know but I only took meds for 2 months (I think you need to be off meds for minimum 6 months before being considered). Will report back here as to the outcome!
You can get your class 2 by issue of a doctor's report identifying the care you received and meds you were prescribed.
Good luck I'm sure you'll be fine
