Girls, does anyone here have endometriosis and could tell me more about it?

I was diagnosed with PCOS (polycystic ovary syndrome) when I was 18, after having a lot of pain and period problems since 15. But since about December last year, those problems have gotten a lot worse and I saw a gynaecologist yesterday who did a scan and said he doesn’t think I have PCOS and that I never did, and he thinks I actually have endometriosis instead. So he wants me to get keyhole surgery to have it diagnosed or ruled out. But I’m still on the fence about it because I don’t know enough about endometriosis or the surgeries that can be performed for it, and google can only help so much. I’d like to hear personal stories if that’s possible. If you’re uncomfortable sharing, you’re welcome to go anonymous if that’s easier.
