I'm 15 and I've basically ruined my life
That can't possibly be true. How do you know you ruined your life?
I know I'm an idiot.
You're just 15 and you have a long life ahead of you.Maybe you think one mistake ruined your life but it's not the case. You'll be fine over time.
I don't think so. I rejected a great guy and decided to date a complete idiot. What was I thinking?
We all have relationships that do not work out. You should not feel like a failure because of that.
