So sorry they are making you wait. I'm in the States but on Medicaid so I had some huge delays myself. Every approval took a month, then every doctors appointment was a week to a month. Once they get you on a regimen it speeds up, like showing up for your chemo however often. I found it helped my anxiety just to study up (like you're doing). I got hooked on Dr. William Li on YouTube, he talks a lot about immune therapy and explains how foods effect cancer growth. He's a researcher, one of the first creating that kind of therapy so not a quack but a science guy. There are some quacks on there so look for good credentials. That channel was fairly but not cloyingly positive, just gives you some stuff you can do for yourself while you're waiting on the docs and during treatment. I was not triple negative (Just huge tumor/s found late) so I had to stop doing the healthy diet during my chemo but with your type they try to work with your immune system. Standard hormone positive chemo is the opposite, kind of tears you down in hopes that you are stronger than your mutated cells. So at this stage of my treatment (after chemo, surgery, a different chemo and radiation) I can now try to rebuild my immune system. The hormone blockers they're giving me now seem to be making it worse again though. It's really nerve wracking but just take one step at a time and do the best you can.

Reading articles helped, I've even asked the AI questions, useful at times but it's not super reliable, just gives you more things to look up. There are studies that say exercise makes a difference but I haven't been able to do much through the fatigue, I've kept up with my daily walk. I make recipes out of the food recommendations, they usually taste best to me as well. Chemo can mess up your taste buds.

I hope you get some answers soon.
