Please tell me how to make it stop?

Girl I know exactly how you feel. I was also in your situation. When you get to your breaking point you will just get enough and move on and then you will truly feel free. I belive in God and if you do then you need to turn to the power of prayer. Also just think that you cannot make a person give you the closure that you need. He may never give that to you and be truly sorry but you do have control over yourself. It is hard but it is only as long as you let these feelings control your life. You may have moments of depession about it but just think like a warrior girl and the enemy is pity and self doubt and feelings about a person that dosent care about you. good luck it takes work to move on
