I've got that very same hill ("Killer Hill"), at the top of which is my house. I can't go anywhere without dealing with it. At the bottom of it is a dead stop major highway crossing. People in cars die there every few years because they can't stop in time. I used to walk up and down it every day, panting and sweating. Now I bike up and down it every day, pedalling R-E-A-L-L-Y slowly and concentrating on breathing evenly and deeply. I walked my bike up it for six weeks before I could tackle riding up it. It still taxes me to my limit, and I'm breathing very hard, but I think of it as my daily cardio exercise and thigh building exercise now. If i think of it that way it becomes a thing that helps me rather than my "enemy".
