How do you deal with FOMO in gaming?

I am a big gamer and quite competitive. I play all sorts of games, from retro achievements to wow to call of duty. I've noticed recently that I get really stressed due to fomo whether it be for a limited award (that just appears on your profile) or some skin that I will end up never using.

My question is how do you guys deal with this? I understand some disappointment will be there for not getting something you want, but I even get it with things that either I will be the only person to see it or care about.

Keeping up with so mant limited events on so many different games while also just playing whatever I'm interested (fixated) on at the moment has been really difficult
