How horrible for you and your family! It is the sort of thing you don't want to believe really happens. I really don't have any advice except to encourage you to do what you need to overcome your fear and live your life. If learning how to use a gun helps, then do it. Personally, I would take a self-defence class with your girls, so that they can have the same some feeling of control too and share the time with you. I have been attending Austin Kuk Sool Won on Pond Springs road for 6 years with my husband. They have a 4 week introduction class and I felt more confident in myself just with that. Many schools have this sort of thing so that you can try the school out to see if it is right for you. God Bless!
