I know exactly how you feel. Ironically I get this from my own family.
I won't go into my family hx with this, since this is not what you need to hear.
When I was diagnosed, in Feb of this year, some people came to me and said, Oh, my God, are you going to die? I was like yeah, eventually, so are you.
People MEAN well, sometimes I think, and sometimes I think they're just mean. Sometimes I think they speak before they think, actually, my sister does that a whole lot. She says some pretty crazy shiat to me, she's 42, I'm 29, don't tell me how to deal with cancer, and that I am over reacting, she's got more years on me than I on her, and she doesn't know what I am going through.
Basically, I've gotten to the point, if they can put it out there, I can dish it back to them.
P.S. I've named my port Carl, I hate him, but he does help me out. I named him after Lorraine on MadTV, her husband's name is Carl.
