Find a hobby that u can engulf yourself in. They aren't worth your time and energy to get all worked up for, especially if they are with and care for someone else. Focus on getting yourself where you wanna go, and not where you've been. The past is gone. The future shows promise when you work towards a goal, and not stay stuck on the current situation. Pray for strength and clarity to get you thru this, and He will help you! No joke!!!
Be glad it's not ur life being messed up cause it suks be glad you are healthy and single get out to the mall and see the hot singles. Sitting at home crying is just avoiding life. Life is far too short to waste one moment, get up and go have fun! :)
Whenever you think about that person, describe the room/area you are in. It takes your mind off of that person. Then, go see an action-packed movie. That's what I do because I am in the same situation right now... Good luck, sweetie!
