Sounds awful. Nothing worse than opening your heart (let alone your home) and then having it returned to you in pain and grief. Did you call the police about the theft? That would be a good place to start. I have been lucky in not having to have a roommate in my home all my life but I can see how it would be a blessing for you. I wish you luck in the new roommate situation and pay no mind to the neighbors who I am sure have nothing better to do then see what your doing and how your living. Hang in there and keep your heart guarded until you can heal and recover from this.
