It's ok to feel that way @Spillsy, it's the shock of life being turned all upside down and round about. I said all the way thru chemo I didn't feel like me, look like me so this wasn't happening to me right!? You just keep putting one foot in front of the other and just do what you can manage. If you're able to go for a walk, great. If not, don't beat yourself up. The fatigue is real and it's accumulative I'm sorry to say. And PS you are so not a wimp - cancer sucks as does chemo and it's shitty side effects. Massive hugs xxoo
