Changing for good. Please help me.

Hello,

My name is Ethan, and I'm an 18 year old male. Weight has always been an issue, and this is yet another new year where my "New Year resolution" has been the same -- to lose weight. Over the years, I have tried many times to lose weight. Dieting and exercising weren't the problem. I've came to the conclusion that it's my lack of motivation. I'll get 2-3 months into losing weight and I'll just stop. I'll wake up one day and have no drive whatsoever to continue. And I won't. Then months later I'll say "Dude, you really need to pick it back up", and the process repeats.

I need a friend; a supporter; and most importantly a motivator. I guess age and gender aren't really relevant. Just anyone that would like to help a person get healthy and completely change their life. Thanks in advance.
