Yikes, what a scummy thing for that person to do! If I got something like that in the mail from someone who I have purposefully broken contact with it would give me chills.

I agree with others that I don't think that your T will have to make a report to the police. If you threatened to hurt yourself or someone else, then she'd have to report. If one of her clients threatened to hurt you or someone else, she's required to report that. She will want to talk about it with you and to make sure you have a plan to keep yourself safe. I really hope you go down to talk to your local police. Even though the person hasn't made an actual threat on your life, it is definitely an attempt to intimidate you. Ugly, ugly thing for someone to do. Take care!
