Vent away, @Sister - we hear you, we feel for you, cos many (if not most) are feeling the same.
When people ask me how I am going .... are you OK? I say "I'm good but my body is stuffed from the cancer meds." If they want to ask about that comment - I will enlarge upon it.
I used to walk everywhere 'fast' .... now it is a stumble. I find that I am no longer able to 'stand tall' - I am slightly hunched over, leaning forward, which is really annoying as it also makes you less stable. Getting in & out of the car is an interesting activity ..... thank God no-one (that i know of) have their videos going!
At least, since I've been on 'the good oil' my hands and feet are not as sore/stiff as they used to be from the AIs.
