Am l dumb for knowing l have cancer but not going to the doctor?!?

I have cancer..Melanoma specifically..I am sure cuz l have a mole on my back and l have all the ABCD symptoms. So it is certainly a melanoma..But l am afraid of going to the doctor..How would my parents and family take it?I am sad,crying all day but something stops me from going to the doctor..I think that it is already too late as l have spotted it 2 years ago!So why even going to the doctor if no hope?
