When you have a friend who constantly asks you to help with their problems, but is nowhere around when you have a problem, what can you do? Sure, you can dump that friend. But you can also set boundaries and compartmentalize your friendships. If you know that one friend is really clingy, tell her she can't call you in the middle of the night for advice, and if she calls at a reasonable hour, tell her you have only 20 minutes to talk, then say goodbye. This approach might sound harsh, but if you don't stick to your guns, these types of people will take advantage of your good nature, and you will get nothing in return.
