Do not....

....ask me about my sickness. I'd cry.

....ask me to do something I initially said no to. I just don't want to.

....ask me to say something I don't want to. I have reasons.

....force me over and over again. I feel pressured.

....again....ask me about my leukemia. Just don't.

When all above are failed to be complied, you would see that I will begin to shut myself from you. And everyone else.
