if it was your login, that's one thing, but it's your mom's.
I would say you don't feel comfortable giving out your mother's login info. You can kindly explain either she could contact your mother directly (which I bet she won't do) or she can sign up for her own accounts.
Not unreasonable.
Yea, I get it. It just seems so nit-picky to me, like I'm punishing her for leaving me. I know my mom wouldn't care. Idk
I will say that there seems to be a bit of weight off my shoulders since she left. I know its still very early into this, but seems like progress.
