Endometriosis

So I've been having issues with periods being heavy and wildly irregular since I first started them and over the past few years everything's gotten progressively worse and I've been diagnosed with endometriosis. It's great to finally have a diagnosis and start finding the right ways to treat it for me but it's not something I can really talk to any of my friends about as they don't quite 'get' it and tend to make well meaning but ultimately non-comforting comments/suggestions. I was wondering if anybody else out there had any tips on how to deal with things?
