My mom has mental illness. I lost my temper this morning when she started with the crazy talk, and told her I wish she was dead.

I set my phone down, trying to cool off, and do other things. She called twice left messages, but every time I tried to call her back afterwards there is no answer. Now it seems like her phone is shut off or the battery is dead.
Please lend me some positive vibes, prayers, thoughts, etc. that she hasn't done anything rash. I'm going over there to check on her in a few minutes.
