remember one thing.. love only improves you, whether or not you are receiving it.
(you owe it to yourself, and the people that love you, those you've made a promise to be there for, or those who have chosen to make sacrifices and gone out of their way to support you, never to put someone else in charge of maintaining your self worth)
love does not wreck the wearer, so the stuff that feels like its eating you is jealousy, insecurity, fear, loneliness, pride, and vanity to name a few.. if its feeling unbalanced, a person that really loves you will respond positively when you do things that are good for you, a person that is in it for themselves will start showing their true colours as soon as they realize they aren't your first priority any more, at which point you'll be emotionally freed up to tell them to take a hike.
