Friends.

Friends come and go if they are taking advantage of you then aren't being a true friend. A true friend would return the same time and effort that you've put into them. If they can't handle that then you need to tell them to remove themselves out of your life. No one wants or needs negative people or energy in their life. When get of them you will feel like a weight has been lifted off your shoulders. If no one wants to give you the same respect then friends aren't needed. Work on yourself then real friends will show up in your life.
