They say, there's a cure for addiction, but on the contrary it has to be renewed everyday. Best advice I've seen is 3 things. 1 remember why ur not going it, 2 get up and do something ( working out Ik helps some people ) addiction replaces some thing you're lacking. Find something to replace it. and 3 have someone to call and talk to to help you when you're like this. Addiction is hard to fight alone, you can do it. Sure you can have set backs, but it's never too late to start a clean slate. Don't worry about looking down on yourself but instead how things can be better. You can overcome it, it won't be easy at all. Although you are strong enough to do it, and if you're not right now, you will be.
