The nausea is so miserable

Oh my God! This is the worst misery so far. All yesterday and this morning I was SO nauseous and throwing up. I think I'd pick the pain over the nausea anyday. I had to sit with a bucket next to me most the day yesterday. It was all I could do to go to the hospital for the Neulasta shot I had to get for my low white blood cells.
Next chemo, the oncologist said he'd put me on stronger nausea meds. He said it's to be expected that this chemo will become progressively more miserable and unbearable as we go along. I guess it kind of builds up in the body.
Anyway, I'll get through this. It's just so disheartening to know only 3 days ago, right before I went in for chemo I felt great. I guess this is the cycle I will learn to live with the rest of the year. About 9 days of misery followed by about 2 days of ok, 3 days of almost back to normal and then I start all over again! Sometimes I think this is all so unfair. I pray about it.
I've been through some of the most horrible things a person can experience in the last few years, losing my mom, almost losing my husband, many other horrible life-changing things and now this!
I think I've always been a very giving person, always put everyone else's needs above my own, I pray, I try to take care of everyone around me and love my family & friends dearly and I show them and tell them so.
God must have a plan. All I can do is believe and trust in Him. It's all in God's hands.
