I'm playing PUBG for years now and always had a good time. I enjoyed the 'tense' moments in the game. But lately, my anxiety is worse and when I play a game now, it creates a nervous feeling in my body. Mainly the stomach area. And it stays there for quite some time after I stop playing.

This must mean my nerves are 'on edge' or 'tired' from all the stress I suppose. Or how else could this be explained? And what is the solution? Give me nerves a break for a while and thus also stop playing this game for a while? 

I'm already sleeping better. Walking more. No more alcohol / porn / reading news. Taking L-Theanine daily. Etc.

What else can I do to soothe my nerves?
