Lost my way

Hi guys. I've been on here since november, noting some decent streaks since then. But I have never totally breaken free. The last few weeks it has really gone south, and this week I've relapsed two times. I know that I HAVE to do this, but still I've forgotten why.

Guys, please give me some input. Why do I need to do this? Like reasons etc, both mentally and biologically. I know it, but still don't. I need to get that motivational foundation back inside of me. Have a great day guys!
