I was in a similar situation - I used Escitalopram for about a little less than a year to help me through some situational stress and ended the medication with the help of my prescribing doctor. The process felt very complicated when I started and truthfully, it was, but I did end up getting my Class 3 medical eventually. It took working with a HIMS AME, getting a psych eval from a psychiatrist, getting notes from my prescribing doctor stating my well-being, and waiting more than a year to get it. The FAA is extremely backlogged. If you can afford it, I recommend using an advocacy service like Aviation Medicine Advisory Services (AMAS) or Left Seat to help navigate the process. I used AMAS and they helped a ton. They offer a one-time consult via email or phone if you didn't want to use the full retained services. You could also call AOPA Medical line if you're a member and they can help you navigate (though my vote is AMAS's paid consult is a better experience if you're budget conscious, having used both.)
Ultimately, my read (not official) is that for non-recurrent situations, I think the FAA has a larger issue with the underlying diagnoses than the usage of Escitalopram. The FAA
just released new guidance this month for uncomplicated anxiety and depression - which could be very helpful for you, perhaps. (I am actually in shock that they revised this. Makes me very happy at the progress, as I thought this would never come, but I digress...)
See the news here:

And the official docs here:
https://www.faa.gov/ame_guide/media/Anxiety_Depression_Disposition_Table.pdf
I would check those docs out and consider contacting a confidential advocacy service like I listed if you meet the criteria listed in that official FAA doc I linked.
All in all - if your case is as straightforward as it sounds by your description, I think you'll be fine. You will need to be EXTREMELY patient and be prepared to go gathering lots of documents, but hopefully you fall under the new rules so it's quick and easy. Good luck and happy flying!
