Hey there, so I have been a "hardcore gamer" for 6 years, and for the first time a month ago, I decided to try and stop. I used to come home from school around 4, play until 7, have a 20 minute dinner and pretend I had a lot of homework, then go play until 10. I felt disgusted with myself about a month ago because I was lying to people to keep up my addiction, and my gpa was at a 3.67. My solution was to stop playing video games except for a few hours on the weekend. Since then, I have kept my resolution and haven't played on a weekday since then. The negative side effect is that I am depressed.
When I say depressed I don't mean suicidal, just a lack of any emotion. My theory is/was that the video games were my way of getting adrenaline and dopamine (however it's spelled) and that because I had stopped, my brain isn't getting dopamine any more. I started playing badminton, got my grades up, started working out more, and yet after a hard workout, instead of the happiness I felt when I used to play soccer, I just feel empty; no energy or happiness, just sitting there existing.
I am wondering if anyone knows how I can get out of this, because it isn't very fun

Sorry for the epic post, and thanks in advance!
