(((HUGS))) I'm so sorry this happened to you!!! How crazy...there are two posts about stolen LV's today! I've also been a victim of break-in & theft and I can tell you that you will get past this horrible feeling.
The police explained to me that many theft situations are just random acts...just criminals looking for easy opportunities. Sometimes it doesn't take more than a slightly open window to encourage a vagrant passing by to come into a person's home & burglarize it. Really & truly, this can and does happen to anybody. Also, it's a fact that the holiday season is when the criminals really step up their shady activities.
I hope you know that you're not alone; many people have experienced what you're going through & understand exactly what it's like. Also, I hope you feel better soon & that you can replace your much-loved LV.
