Saying no has been an issue for me for years. I've always "been there" for friends and have asked for little in return. When I finally did ask a favor, guess what? The friend said no! That was a wake up call for me. Maybe you need to ask and see if anyone is going to be there for you. When you find out it's just a one way street, you'll wake up quick. I can now say no. Sometimes it's still hard to do. I think about who is doing the asking before I respond. Some people are just takers without any conscience at all. Be strong.
