I know I am not in your shoes, so it is, as others have said, hard to give advice, but I agree with Rohag, and I also would keep going if not for help in feeling better than to make sure that there is someone other than yourself who knows that things are getting worse. Isolation is a killer in this disease. As to the devil....

Maybe when things are feeling so bad, and you feel so cut off from peole and God, it might be a good idea just to leave off of pushing the prayer at all right now. Just let that be. I know for sure that the Devil isn't interested in your wellbeing any more than depression is.
Thats's all hon, I'm so sorry things have gotten so bad so fast. Nucking Futz is also right, and going off the meds can make things that much worse. hang in there and I kn ow it's hard to nag caregivers at this time but plese try to do it. You need their help and they don't seem to have realized you are doing so badly. Huugggggssss and prayers, dear Gingercat!!!
