Endometriosis

So i recently got diagnosed with endometriosis(im 16) and its getting worse. They put me on the mini pill because regular birth control will interact with other medication i take and i would just like to know if any one has ever had endometriosis could tell me how bad it could be and what it can result in or what it resulted in for you because i do know that my doctor said it can cause infertility, ovarian cancer, or a hysterectomy and ive been worrying my self to death about this whole thing bc i am in constant pain.
