Finding another job that offers you the opportunity to learn new things is what I'd recommend in the short term.
Longer term, it helps to have some kind of goal. What do you think would be an awesome job, even if you couldn't get it right now?
Maybe working on some VR/AR tech, or at some Antivirus company.
I did some OverTheWire exercises, and was learning about creating viruses. But, I ultimately ended up playing a lot of Dota.
I eventually did a Master's degree in infosec. Spent a while developing security products, then moved over fully into security architecture. That's been ten years now and I'm getting itchy feet again!
But don't beat yourself up over playing games, if that's what you do to relax. You can't be on all the time. I go though phases of just going my job, then I get enthused by something. I'd honestly just find another job in the short term that gives you the opportunity to grow in some way.
