For some people, myself included, we are well versed at doing things ourselves but we are terrible at asking for things. This kind of person will typically give all they can in the service of other people even to the detriment of themselves, they always go the extra mile to help or accommodate the needs of others but never allow others to help them with their needs and wants. This is the self-dependence trap, being so independent that we lose our ability to ever be dependent on anyone or anything but ourselves.
