Courage to speak up for myself

I never liked these sentences 

"Can you do it?"

"Wouldn't you feel tired?"

"Would you have the stamina to go?"

I request the person by saying that 

Can you use these sentences only when I am in a wheelchair?

The person replied, saying, "Noted." 

Somehow I felt the person respond to be cold cause of our history that we were never close or connected, there was always distance between us, it was the person who put up the wall. 

The person didn't acknowledge the word I use "wheelchair" it tell a lot about the person who wanted to connect who doesn't. 

I am proud of myself while at the same time heart broken (two feeling at once)
