Why not get a job related to gaming if thats what you seem to like doing mostly? Or just get a job first, any job, I find that when you are doing something you dont really like, it forces your brain to come up with a list of things that you'll want to do instead, pick one from the list, and find a job related to it if it isn't a job. Just do something, if you don't, nothing will change.
You just need to try working full time. There should be lots of jobs out there. At least you do not have a health problem. You can see IMH NAMS - national addiction management services before your addiction to gaming get worse.
