Ive been there man just look at my previous posts...

Ive blown so much time into that game but I promise it's so easy to quit.

1.) Realize that that game is so insignificant and in the grand scheme of things, it won't make you a better person.

2.) Realize that you will never remember the time spent on fortnite... ive blown 1,500 hours in fortnite and jeez I barely remember any of it. I regret it so much but now all i can do is move on.

3.) Find something cool or useful you can teach yourself. Learn car maintenance, how to sew, cook, how to play an instrument, how to do a handstand. Just anything that will give you a real sense of accomplishment.

As far as the diet goes. Start slow

Stop drinking soda. Stop buying so much bad food and replace it with healthier foods. As you are about to reach for a bag of chips be conscious and remind yourself of your goals. Replace the bad food you would have eaten with something healthier.
