Chocolate cysts (endometrioma)

Tr
Day two of period I was experiencing severe cramps and leg spasms. I go to the emergency room and receive an ultrasound come to find out I have a cysts on my overy which is a chocolate  cysts or endometrioma. I didn't think anything of it until I started doing research and realized it is a form of  endometriosis. I have just applied for insurance to get this removed and was wondering if anyone developed full blown endo after finding out about an endo related cysts? I am 23 and have never experienced any thig like this so please ladies help me out! Thanks in advance
