Welcome to the website and I am sorry to hear what you are going through.
Interestingly we are all scared of chemo, I read it time after time on here and I so remember feeling petrified of it, I was so happy when my oncologist told me that I didn't need chemo and then when she said no that was incorrecxt I would need it my world came crashing down.
I finished my chemo in April and like the others I survived it, its no walk in the park but I kept focusing on the good it would do me.
MY advice for anyone facing chemo, take all the meds given to you don't be a hero, drink plenty of fluids, have diarrhoea meds on hand just incase, hydrating drinks in the fridge, anti nausea meds and rest as much as you possibly can.
For me I found the dex was an issue, if I rushed out of bed I would vomit and the extreme fatigue was scary, at day 5 I would get diarrhoea but all these things were manageable.
I am now 3 weeks into my radiation and chemo is a memory.
Take care and good luck with your treatment.
