In my own opinion, you would be a great advocate because you have experienced so much and you are rational, compassionate and well-spoken. I did not do much looking at the links in that Goggle search, but it would make sense to me to look at the types of openings available and then see what specific credentials (college or whatever) are actually required. Also, it would seem to me that taking on an entry-level, advocacy-related position of almost any kind at all could be a good way to get started in order to build a resume' that could ultimately get you into the exact kind of work you actually want to do.
