I am sorry. It sounds so aggravating.

The only thing I find confusing is why you gave your sister therapist’s number if you didn’t want them to talk. I can trust my brother with my life yet I’d not give him my therapist’s number because he has no business talking to her. If your family isn’t trustworthy, why give them therapist’s number? I wonder if L called back because she thought you are ok with it as you gave her number out. Normally if you don’t want people talking to each other, you’d not be sharing their phone numbers

What’s your sister is trying to do? First she gives you wild undomesticated animal (even if it’s cute) that’s not legal to keep at home in your state (she breaks the law so she wants you to do the same??? Isn’t she the one getting arrested driving drunk with kids in tow? ) and then she wants your t send you cards via sister’s house (why???).

The whole charade is just off. This is just all kind of bizarre. I’d not trust your sister with anything, certainly not with other peoples numbers. She needs to refocus

As with what to do with t. I’d insist she explains why she called your sister back (possibly she thought you were ok with it). Continue creating a list who is ok to call back (glad you are already doing it). Only give t’s number to emergency contact people. And I’d talk to my sister about it too. No more nonsensical ideas coming from her
