Any advice please?

Does anyone have any tips for coping with Endometriosis? I have yet to be diagnosed but two doctors are certain I have it. I was due to be diagnosed but my appointment was cancelled due to the coronavirus. I am suffering terribly with pelvic pain, pelvic and rectal pressure and SEVERE pain during sex. What do you do to help ease the pain? Do you take certain medication? Are you on a specific diet that helps ease symptoms? Please help me I’m desperate. Thanks.
