Glad you are feeling better. I only had Covid once, back in 2021, but in my case it was severe and awful. I was in the ICU in the hospital for about three weeks, and still felt awful when they released me but I wanted to go home SO badly and they really needed the bed for even sicker Covid patients at the hospital (so I did go home as soon as they'd let me).
I still have some minor Covid symptoms (little bit of brain fog, coughing up gobs of mucus most days, zero energy, sleeping and napping a lot) so I guess that possibly I have an extremely mild version of long Covid. But this is a "walk in the park" compared with full fledged Covid IMO.
I never took SSRI's so I can't help you there. I am fortunate enough to be probably the happiest 75-year-old who ever lived. Anyway, my advice is to keep resting, eating nutritious foods, and taking very good care of yourself until you are sure that you are completely over it.
