Left my prev company 2 months back but still have FOMO

I left my company 2 months back because I felt I hit a ceiling/reached saturation when it came to learning and the product + I wasnt fine with the biz model changes and other decisions. Hence decided to make a switch.

The people (close knit APAC team), lifestyle (events, work travel, hotel stays), them inaugurating a new swanky office today, an annual event coming up which Ive always looked forward to being part of

⬆️All this has started giving me a FOMO and I sometime start questioninng myself whether I made a right move.

I shifted to another fast growing company, good pay, great product. I am still going through my trainings/enablement. The real work hasn’t even started yet so dont see why I am questioning myself.

Not sure why am I getting this FOMO. Can you help? how do I get out of this fomo?
