Chemo isn't like it was even a decade ago. Yes, there are wide effects but not everyone gets them and they are much better managed. I've had two chemo experiences a decade apart and I didn't chuck up once. Considering I get so carsick I can't travel in the back seat and the smell of anything really rotten makes me heave, I was pretty surprised about that.
If you need chemo, it might be worth asking about having a port inserted. (It's ok to google stuff like ports, look at technical stuff, and don't get distracted ) For me, in 2016, that little box under my skin made the whole performance doable. My veins are so bad and I have developed a well deserved needle phobia so to know I wasn't going to spend months having people jab at me was a huge weight off my mind.
Surgery is not fun, but it's rarely as bad as you expect.
I know, this stuff is challenging. It's a shit of a disease, but we're living in the best place in the world if you end up with it. Keep a list of questions and keep plodding on. Mxx
