Welcome @Livo,
Sorry you have to be here but you will find a wealth of information and warm support here. The start is the hardest, we all understand how you feel.
The oncology appointment is incredibly daunting. I remember how scared I was as well. You will be bombarded with information you never dreamed you would have to ever worry about. They will give you every side effect you can possibly get. That does not mean you will get all or even many. It just depends.
Chemo sux, but it's probably not going to be quite as horrid as what your brain will conjure up. I had the ever popular AC T chemo. I managed to work through most of it , run my farm, renovate and do all my usual stuff, I kept my hair with the cold cap (do you have access to one of these to try?) and my family had multiple social events starting at that time and I had a fantastic time at all of them. Some days were crap but there was a lot that werent.
Once you know which chemo regime you are having there will be many on here that have had the same on with lots of helpful advice.
It is incredibly scary at the beginning. You will be ok. Promise.
All the best lovely
