I've quit LoL for like 6 months, and it's still on my mind very often

I miss playing LoL with my friends so much. I just want to buy a gaming pc again and hop on discord. I feel empty. I have another hobby, piano, but it just doesn't fill the lack of dopamine LoL left.

I know why I am doing this. Not to focus more on my dead end college degree not to be healthier, but for my girlfriend. There is nothing else stopping me from going back in gaming. I feel so bored, and I feel such a big amount of FOMO. I keep thinking about how much fun I would have on discord with my friends right now.

Edit: I want to add that this is atleast as difficult as it was to stop smoking. I feel like dogshit.
