I think it sounds as thou it could be endometriosis nillabean. If so the surgery is sometimes called a laparoscomy I think it's called. I had one a few years back and was pretty straight forward. Only issue I had was a bit of shoulder tip pain due to the medical gas they use to inflate your stomach x
Glad appointment went well apart from that xx
Aww wunna I know the feeling of not getting as much support as you would like and it can be tough, and yeah I also agree people tend to brush it off as hormones and don't take things as serious as I'd like them to. I find it makes me feel a little resentful or that I'm very Lonely.
On the other hand I do suffer with mental health which I don't think helps as I can over react a little or not notice when people are offering help and I'm just too frustrated and wound up to notice
silly me. I hope you can find a way to resolve how you feel, and don't forget we are here to support you in what ever way we can xx
