That is because you have lost something or someone you held very dear. Now you can't seem to get over the loss that marked your soul, and the only solution is to go after the one person who brought all this pain to you. Chances are you are angry inside and you bottle everything up and don't talk to anyone about it. People may want to help, but you think that they can never understand your pain and only get frustrated because of this. But it is important to see all that you have left and be thankful of that even if you have lost something great. It may not be true that Times heals all wounds, but with time and talking about your feelings, maybe the hurt will ease.
