This sounds like my kiddo. So much. I'm sorry.
I noticed that about the payment and wondered if that would not work for her with her situation. It wouldn't work for my daughter, I know that. She can't keep a job, but is not on disability. But you not reading the rest of her ranting text - BRAVO! My daughter often uses texts because she can't seem to communicate verbally (she screams a lot and hangs up on me). Cellphones aren't just bad for teens, they can be terrible for adults with issues, too.
Anyway. I'm with you. And hugs.
