Endometriosis

So I’ve been suffering with chronic pains in my back and stomach for about a 6 months now. Spent 3 weeks in hospital with a burst ovarian cyst. Was admitted again just 2 weeks later as I could walk because the pain got so bad. It’s now been a month since all this happened. I’ve been back to the doctors because the pain still isn’t going and I’ve been referred to a gynaecologist because she thinks I have endometriosis but it’s a 6 month waiting list. I’m in agony again but it seems like there isn’t anything anyone can do. Don’t want to book another doctors appointment as it will be waisted because they can’t do anything there. PLEASE can anyone suggest something for me to do because this pain is killing me now! Frustration is at maximum level! 😩☹️
