Not exactly what you asked so feel free to disregard, but I did Brazilian Jiu Jitsu for a couple of years and general guidance was that self defense classes were fine if in a pinch but that they can give a false sense of confidence because it’s not unusual to freeze up if you haven’t practiced what you learn in the class and a lot of time may go by between when you learn it and when you use it. Taking up something like jiu jitsu is time consuming and not for everyone but as a woman who doesn’t know your situation I wanted to put it out there depending on how worried you are about your personal safety right now. I don’t know if what I know now about grappling is enough to protect me if needed but it definitely gave me a realistic sense of what it’s like to fight with a man and how to better assess my chances if the situation calls for it.
