Hang in there Bill, assess and re assess I have been there many times with my son who Drs do not want to further treat complications due to being severely physically disabled as a quadroplegic with manic (gene from me, mom).
If you can no longer care for her than that is a dicision between you and God.
Do not allow "proffesionals" to push you into a decision.
Alot of folks are having flare ups around here lately it seems with coping with mental illnessess, keep up the fight.
We will keep up the prayers, ok.
I do not know all your details, but go with what YOU know is best.
We constantly fight the "world" in that I should turn my back on my son and get a new life. I say NO this is what I have done for 25yrs and dispite the rough days usaully brought on by outsiders I perservere because in my heart and stubborn soul it is what I choose to do and truly believe I am doing God's will.
Hang bud get some rest, a few days of turning off the phone and the world and just careproviding and resting can renew ones ability to cope.
If at all possible get some respite care so you can take a long walk or a days drive away from the situation.
God Bless
