Petechiae Lung Cancer Why Doesn't My Dad Notice That I'm Sick?

Why doesn't my dad notice that I'm sick? - petechiae lung cancer

I'm a hypochondriac, and I know, but I think I have the right to be. My brother had leukemia when I was little, maybe four, is in remission. I have many symptoms. I'm not hungry, I'm always tired, my bones and joints ache, I'm still coughing as my lungs feel irritated, and I have all these red dots on my feet (very small, so I do not know if petechiae ). He showed me the red dots on my father, and he said they were shaving. He also knows my pain in the joints and does nothing. I finally convinced my parents scheduel physical examination for me, but that's all. If it were not my father be very careful because of what happened is my half-brother? Should not freakING when I make a lesser evil? Why is it that my parents seem to not look at me when I'm sick? Why do I care for me every time? I'm only thirteen years old, but I know I am a little sick. No cancer genetics? Please help me.
