Not much time

Hospice has give Louise at the most 2 weeks to live. She doesn't remember anyone and she won't eat. A part of me is so pissed. Why even bother praying? I feel like if God was going to heal her he should have done it by now. My heart is literally broken. I hurt so bad and I wonder why this is happening. I feel like such a hypocrite sometimes. Like one minute I trust God and I keep praying and the next I think "If God really cared he wouldn't have let this happen." I have nothing else to say. Thanks for listening to me vent.
