I feel a lot of guilt

I feel guilty a lot of the time. I feel guilty my invasive treatment is done while others suffer. I feel guilty my BIL died & I'm still fighting. I feel guilty I got to go through radiation, & he didn't make it that far. I feel guilty I have full medical coverage because of the accident of birth while others struggle to pay for treatment. I feel guilty my prognosis is good, while others face their worst fears. It does me no good to feel it, but I do none the less
