I habitually lie and cheat, and I have a gaming addiction.
Have you tried to stop playing games?
I just can't stop. I've had them since I was a kid.
Those sound like pretty serious problems. Addictions can be really hard to overcome, but you should look into seeing a professional to help you get your life back on track.
Therapy is for losers.
I am sorry you feel that way, as therapy has been beneficial to so many people . You could try and quit gaming cold turkey.
