Oh wow! That is so scary. I'm so sorry you have to deal with this. I think I'd sleep in a chair in the living room with a big gun in my lap. I can't imagine how anxious you must be. I'm glad you can change the locks right away. Chances are, they won't come to your house because they know you're likely to be ready for them. They'll prey on some other unsuspecting person. That door jam lock is a nifty invention. That should make you feel better. And yeah, if you have a holster, you can keep the gun on you all the time for a while...until you feel like things have settled down. I think it's a good thing to go through scenarios in your mind before you would have to use a gun so you're sure not to fumble or anything, should something happen. (which I doubt) I think you will get past this. Get some support from someone to help you sort through it all. I just can't imagine what this must do to someone. I'm so sorry. (((hugs)))
