I think that mental separation between what is, versus what it feels like or seems like, can make it more manageable some times.
Depression is a part of the diagnosis it seems, moose eater. I certainly struggled with its presence throughout treatment. When depression gets mixed with fatigue, uncertainty, doubt, and a mind searching for sense, it was mental separation that got me back on track. I am not my disease in effect.
Do you feel like you are in a dreamland? My trip to the cancer center was solo. It was something I made alone for a number of reasons. A 5 hour drive to get there was plenty of time for my brain to escort me to places I didn't want to go. I checked into the motel that offered a discount to 'cancer patients'. The only thing I remember about that evening was buying a bath mat at a nearby outlet store (never now when you might need one, right?)
Safe travels
