Recently diagnosed with endometrial and cervical cancer. I've lost my appetite and struggling to eat anything. What can I eat to keep my strength up?

Hello. I have recently been diagnosed with endometrial and cervix cancer. Not sure how long I've had it, hoping not too long, but it is a fast growing type.  I've really gone off food, and am struggling to find anything to eat.  Does anyone have any suggestions on what I can eat to keep my strength up please?
