Endometriosis?

I was just diagnosed with endometreosis, and the doctor's didn't really tell me too much about it. Is there anyone who has this condition that could give me an overview of how to deal with it and make it a part of my life? I'm only 15 and I'm scared to death. It runs in my family and everyone that's had it has had a full hysterectomy. Will I still be able to have children? Please help! Thanks!
