What is the cause of my dark circles and how do I get rid of them? (photos)

I have struggled with deep discolouration and dark circles under my eyes since i was 9-10 years old. They arent genetic as none of my family members have a history of dark circles. Im now 18 and theyre still here. I dont know how to get rid of them or what is causing them as i have tried the potato remedy and it didnt work. It makes me look tired and unhealthy and it bothers me a lot. The dark circles carry on onto my eyelids as well. Any help??
