I have a hard time dealing with the guilt of destroying my body and becoming disabled

Long story short, I picked up running as a hobby a few years ago only to get injured and have that injury turn into arthritis. I still feel pain just from walking and standing, and it limits my quality of life now. I can’t go to a single doctor visit not without the doctor screaming at me about how I should have been more careful in the past. I can’t get over this guilt because this is completely my fault and I should have been smarter in the past
