Hi and welcome!

The best way to get over this person is to fight off the tendency to isolate yourself. Not having anybody to talk to, especially while you're going through such a tough time with heartache and all is really self-destructive. Even your health can be affected by it. I have a tendency to isolate myself too and I've noticed that something happens when we do this.. we start thinking too much about ourselves, even give in to self-pity! We weren't made to live alone so the best way for you to get over that person and to start feeling happy about yourself and your life again is to give, give, give! Stay busy, look for ways to help others, to make new friends, to make a difference in someone else's life, and you'll have absolutely no time left to think about that guy again!

I hope you get over him soon and that you find peace.
