Changing topics?? Selling out?

So I've been struggling with my thesis. I started to move forward to connect with relevant people to conduct interviews on Depo-Provera. I haven't been getting any response, which was particularly disheartening to hear that from the activists. I have been quickly losing motivation because I was struggling with that "so what" question. I meet with Chris London in our department and we went over the topic extensively. It ultimately came down to the fact that I doing this project just for myself. While that would be gratifying endeavor, it is not helping me with the motivation problem. I presented the concept of mapping as related to my job. Chris pointed out that my thesis was not going to be used by anyone but me, which is not a bad thing. However, I think my lack of motivation is the desire to engage the organization I'm working with in some of the critical thinking discusses I have been having in grad school. He also noted that the mapping tool would provide the opportunity to engage field staff in changing power dynamics between head quarters and field projects. I am already building a project in Tanzania and may have the opportunity to conduct first hand observation.

At the moment, I'm feeling energized about this topic in a way that I have lost about my original topic. Am I selling out? Is this a legitimate alternative? Random thoughts?
