There isn't anything all that wrong with smoking some pot and playing video games. Just make sure you're still taking care of yourself in other ways.
Keep clean. Cook your own food. Exercise, get fresh air. And yes, play some games, while high if that's what you prefer. All of that is taking care of yourself from a physical and mental health perspective, so you don't break down, or, ideally, panic while looking at schematics.
Therapy isn't a bad idea at all, but if you're resistant to that, check those other boxes of self-care and in the process you may gain a few healthier habits.
That prior paragraph is all me - I've always avoided therapy and have had a couple of breakdowns, including a lost decade. I'm now fifty and relatively happy with my life, but only because I did put in some work on myself.
You're off to a good start with yoga and hanging out with friends. Figure out how you want to fill this time, and enjoy yourself. Dabble in things. Find new passions. Life doesn't give you time off like this often.
