Help por favor

I'm Paul and I decided that I'm going to do NoFap for the rest of my life.... I guess I'll update this regularly but first here's a little backstory.

I was a successful runner in high school and smart and the whole bit. I'm going to be a junior in college now and I run xc and track as well. Running is a big part of my life. I started fapping my senior year of HS and haven't stopped for more than ~10 days. I've tried before to stop but failed. Last year I was suicidalbecause I felt insignificant because I was running poorly and felt guilty from fapping. I think fapping has a negative long term effect on my running ability and it was compounded by depression and laziness and overeating.

So, here I am, slightly recovered, and any encouragement/tips/help would be greatly appreciated as I go back to school in a week and hope to have a good season and rid myself of suicidal thoughts
