Look if you wanna feel better it will take some discipline. Im not really the one to talk about this but I promise you it does work. Your addicted to her and you are having withdrawals. The human brain is a funny thing but trust me on this. You need to work-out. Lift weights, do pushups, run in place, anything you can for about 15 minutes and you have to BREAK A SWEAT or its not good enough. Do this twice a day. Be sure to do lots of stretching first and the time used for stretching does not count. Stretch alot and often as possible.

What you will find is you will strengthen your mind; as well as your body. You will begin to feel better after the workouts but it will wear off quickly at first. Don't get discouraged. You will also need to turn off all TV radio, etc, except lights and meditate for another 15 minutes, doesn't have to be right after, can be later that day. Sit in the middle of a room and close your eyes. Make sure it is quite. Sit on the floor with your legs crossed and try to clear your mind. Empty your thoughts and invision you are somewhere else, calm relaxed, on a beach with soft waves rolling in, clear water, soft sand.

Drinks lots of water, and eat less carbs. You will feel better I promise this helps. You might take this as a learning to break up experience. Because most of us don't stay with one person our whole lives. If you love her let her go and try to be happy for her. Shes trying to do what is right for her.

Good Luck. Its never easy.
