1) BLOOD TEST as the experinced members suggest.
2) Do what's necessary to brink your body levels back to normal.
3) take a week vacation and go enjoy somewhere. If money is issue go to family asnd spend time.
4) Reconnect with your old boys. They are the best to get your mind of the girl.
5) Do things for your self. Workout for your self, earn a living for your self.

by the way did you really love the girl or did you love her body?
Coz both are hard to get over but the body can be replaced much easier......Oh and cold turkey on the girl other wise it
gonna be more depressing to find her ****ing another guy soon..
