When I was younger, I was totally addicted to gaming also.
We are talking back when Nintendo released Zelda, Castlevenia etc.
The I replaced my addiction with Alcohol..
Then came Diablo, Counter strike, etc. I started playing hard again, but this time I had Alcohol and pot to enhance the experience. Now these days I only play a little, with my son. He is 7 and developing my addiction for gaming!!!
So I force him to come outside and play. I let him play half an hour a day, and skip days as much as I can.
Glad you posted, address this now and save yourself 20 years of misery. Find new habits, healthy ones, hunting, fishing, sports, anything.
Limit yourself to just a little gaming a day, let's say one hour.
