I think what you really need might be to make new connections. During difficult times in my personal life, what helped me most was really finding some community. I started online, on Reddit and Discord servers for Make Friends Over 30 and others (https://www.reddit.com/r/MakeFriendsOver30/). I'd highly recommend it. Also, finding things that get you out of the previous patterns you had for awhile. Gaming will be fun again another day. For now, go join a dart league or something (anything) to get around other people.

Sorry you're dealing with this. Hope things brighten up for you a bit.
