I think Your best friend is only looking out for your well being. I know it hurt your feelings but you have to understand where she is coming from
I am so sorry that you are having to go through cancer treatments.
I think you are probably being a lil sensitive considering what you are going through and understanbly so,
I just went through a breast biopsy and I was very sensitive to things my family would say to me and that is just a biopsy. I cannot imagine how sensitive I would be if I went through cancer treatments.
I think once you have gotten your strength and had all your treatments you should just treat yourself and go visit your friend. You are in my prayers and a big hug to you! Take care of yourself
