Which degree is for me: MSW vs MFT vs PsyD?

I am interested in working in a field somewhere along the lines of counseling. However, I am not entirely sure which degree I should pursue in order to do the type of work I am interested in. Ideally, I would like to work with domestic violence victims either at a women's shelter or through some other means. Which degree would be best for that: MSW, MFT, or PsyD?
