D.H.
I so know how you feel. I've had my car broken into and my HOME! Knowing someone was in your home, touching your stuff, well, it's quite unnerving! It will pass.......just do what you can to feel safer.......Don't let one person run your life.....which is what they are doing right now.
If you feel better, get an alarm system for your cars and your home. We bought camera's and put them up.......Luckily, the second time someone broke into our home, he left finger prints and he was caught. Not that I felt any safer.
I make sure we always have a big dog in the house as well......it's part of my need to feel protected, even tho I know he can't really "save" us..........try not to dwell on it if you can and remember, everything happens for a reason, even if we don't know what that reason is at the time.
Hang in there and look at what you have in your life, not what you don't have or what was taken from you.
Good luck and take care. If this doesn't get better in the next 30 days, be sure to seek some counseling, you need to make your kids feel safe, and they know when Mommy is upset for whatever reason.
My prayers are with you.
