Oh yes. Some times I just cry at nothing. It's a side of effect of chemo and pre treatment drugs, but also of the stress of having cancer, how it up-ends our lives and how we view ourselves.
Be kind and love yourself, go with the flow. It it gets really bad speak to your oncologist about a consult to see someone who specializes in cancer patients. I find talking to my counselor really helped me deal with the day to day issues I was having. I also got a Pharma consult and am now taking low does of meds to help keep me stable.
Yes being strong is good. But we need help we can not be strong all by ourselves we need support, being strong is asking for and getting that support.
