Remove things that remind you of her and go to the gym…Force yourself..it will do wonders for your body and mind….Will she love the person moping around or someone who is rocking a kick ass life…transform your life into something positive and your body is one way to do that..it improves you physically as well as mental clarity..in time you will get over her…I too have been there, to have no energy, where every song puts me into tears…but force yourself…do it day by day…spend for yourself…get a trainer or instructor for a month to force you to go to the gym because you paid for it and it may go to waste…Find that little anger within you that she left you and let it out at the gym…You will start healing…and no contact or knowing what she is doing..it is her life..her choice…each of you made mistakes in the relationship and it takes maturity to make it work…you are still young, the time will soon come when you literally will feel that the world is your oyster and you can do anything…Good luck and keep pushing yourself…
