Most Helpful Guy
Sadly i've been in this position more than once. And the only thing that helps is time.
Gradually you'll stop obsessing over them and life will take over and eventually you'll be fine. Best thing I found is keeping busy. Hanging out with friends, reading, out for walks... all helped take my mind off.
Now I can think about them and not dwell on it.
Time really does help. Give it a chance.
