Is she trying to ensure you go to IP (by not filling your meds and thus letting you get worse) so that she can file for custody over you again? Basically, "see mr. judge? I told you! She won't even pick up her meds! I have to be the one to do it now!"

Sorry again if I'm being suspicious. I just don't see why she couldn't tell you unless she had an emergency or something. It takes like 2 seconds to send a text message.
