I would suggest getting some additional training such as PPIH/PHOH [Personal Protection Inside/Outside Home]. In addition to book learning about various self defense scenarios, these courses have some hands-on training where you shoot can practice. They also address emergency planning with your family and multiple BGs.

Some people dislike the "What-If" or "What Would You Do" posts on this forum, but they can be valuable, because they get you thinking about what you would/should do.
