<human>: Summarize the given text in a few sentences.

So here's my story in a nutshell:
I have recently been diagnosed with Stage 1A of Ovarian Cancer. I started chemo last week and it's really bitten me in the behind. My BF has been the most amazing and supportive person in my corner and I am extremely grateful that I have him, but at the same time I am scared that this will be too much for him. He wants me to lean on him and use him as my support system but I don't want it to become too much for him. I have spoken to him about my concerns and he says he's here for the long haul but all this toxic stuff in my body is causing me to feel pretty bad and low.
