Well hey, some people with BP are able to turn to stuff like CBT and other management methods and avoid medication, some are not. Some people with BPD wind up needing medication in order to completely cope, some don't. Since you are researching, you are also likely to come across different articles that debate against or in favor of medication for BPD. The way I see it is that different people are well, different, and different methods will work better or worse for different people.
