That fine line between helping people in need and becoming a crutch for people who refuse to make necessary changes is difficult. I also worry at times whether my constant struggles with pain and food allergies make me a burden on my friends. I don't want to be the guy who always complains, but we're supposed to be honest about our struggles, right? I also hate it when other people put on a superficial facade of "everything's fine," or ask how I am doing as an empty social gesture.
One of the books I occasionally see people borrow at the library is entitled Boundaries, written by Henry Cloud and John Townsend. People struggle with codependency. Those who study social problems and economics describe how some people rely on benefit programs to avoid addressing personal issues. I know a few people who became romantically involved with toxic people, and now have kids as a result, leading to greater complications. We humans have a lot to deal with, and no one teaches us how to better ourselves. We have to struggle to learn.
