I'm 21 and having a hard time overcoming a few addictions. I smoke and drink a bit heavily, and still have a few other things I need to work on. I'm a good looking guy and can get women relatively easily, but I'm not using it to my full potential. I've gained maybe 15 lbs over the past few months and I've dipped pretty low. Haven't lifted, been eating like shit, and indulging in unhealthy habits. I'm struggling to climb out of this hole, but I'm afraid of giving everything up and if I'll truly be happier afterwards.

Can anyone give me some insight on their own personal experiences and how you may have dealt with similar feelings?

Thanks
