It seems like you've had a really tough day and I know how it is to be feeling well then all of a sudden, poof, the negative thoughts come in again and scare you with the notion that all the good was for nought.
Just remember that like today when you woke to the wretched voice and sad notions that tomorrow you could wake to it all being good again. Life and the illness is like a rollercoaster, you just have to hang on through the ups and downs and eventually it will come to a place of peace and rest again, before starting the trip all over.
Take care tonight special soul.
