Went about 3 months without playing anything then bought a gaming laptop

I’ve had a very strange experience. I figured that after getting back into gaming I’d instantly be hit with a dopamine rush. Been the opposite for me. Can’t enjoy anything. Tried a couple new games and got bored quickly. Played just about every game I used to play all the time and felt nothing.

The problem is since quitting I’ve had a hard time sleeping and as soon as I started gaming again I’ve been sleeping great. I limited my gaming to nighttime only whereas before I would play as much as possible. I’ve factory reset the laptop twice since getting it a week ago because I’m so torn up and indecisive about it. I guess I’m going to return it even though I’m worried about sleep issues but I guess I can try to do other mentally stimulating things at night instead like writing. And returning it would be a huge financial burden off my back obviously.
