Want a friend to hold each other accountable.

Hi, I am 18 years old. I want to lose 15 kilos, become a good runner and learn to eat healthily but I can never get myself to stay motivated. I succeed for a week and then I give up for a while. Then I decide to try again and it is an ongoing cycle. :/ So I want to start fresh and I want to have a friend or friends to hold me accountable for what I eat and the exercise that I need to do We can talk to one another and hold each other accountable so that we succeed. :smile:
