Get out of the house and find something else you enjoy doing. You'll be much happier that way in the long run. It seems as if you're using video games as a crutch. Well... Maybe stow it away somewhere for a while... See how long you can go without playing. You might not miss it as much as you think you do.
Yeah. Sounds like you need to get out of the house more. Are you interested in anything outdoorsy?
Hmm. Well there's lots to do... Photography, walking, hiking, biking, swimming, etc...
I used to play all day every day when I was trying to not think about my life. I lost interest in gaming when I started to have more things to do, more friends and purpose.
Get new friends :)
seriously though... I feel like I have wasted a lot of time when I was gaming. Go for a walk, read a book... You will feel better mentally.
What are you playing? Try reading again.
I never played that. I used to play world of warcraft. Now I play minecraft with my 12 year old brother sometimes and that's it. You can stop if you really want to. It will be hard at the beginning but it's worth it. Everything in moderation is the key.
