Aww sweetie. Love can be so hard and I know you must be hurting right now. There really isn’t a magic way to get over breaking-up. You just have to give yourself some time and to try not to see it as a reflection on who you are. Don’t let this destroy your confidence. You are a beautiful young woman.
I always found it helpful to get in touch with my friends and go out and do some of the things I loved to do before I had a boyfriend. Go and have some fun. Get on with your school work. Keep focusing on the things that will help you to become a better person and to be a fantastic role model for other girls about how to deal with breaking-up with class.
It won’t help to say this but there is another boy out there for you. Learn from this experience. Lovely to see you here too.
