Stop thinking you'll never get through it. You do and in the end you're even happier than you were before.

 Friends don't treat her the way she treats you. She's not worth your time and effort. Dump him, ditch her, find your real friends, and focus on helping yourself, not others.

 Listen to your friends and family: if they don't like him, he's bad news.

 Don't take him back, its not worth it. You will regret it later, when you can't trust again.

 He'll regret leaving you.. Don't worry.

 Get your anxiety under control. You have it easier than you think.

 Don't settle, because there will come a day when you will become unhappy and that isn't fair to you. Keep all your options open.

 Boys aren't everything, study hard and become a vet. It's better than this.
