Endometriosis

Kelly
Ladies,
   Has any of you ever been diagnosed with endometriosis? I'm going to my gyno in a few weeks because I have every symptom of the condition. My periods have always been super painful; just last week I missed work because my cramps are so bad I could hardly walk, I was throwing up, I seriously just wanted to die. Not really lol but you get what I mean. 
I'm trying not to freak too much about it, it could be that I just have really harsh periods but.. What are the treatments that your doctor gave you after being diagnosed with endometriosis?
