Please help me save my sweet Dinah

Dinah is my heart and my whole world. She is the sweetest, most wonderful girl. I love her with everything I am. Unfortunately, she has gotten cancer three times now. After the first two rounds of treatment and a year upended by domestic abuse, I'm flat broke. I've found two more tumors and she needs another mastectomy as soon as possible- she may need chemo as well. She is only ten years old. She loves life. She loves exploring outside, lounging in the sunshine and would play nonstop if she could. She isn't ready to leave this life and I'm not ready to lose her. She's my sun and my strength, without her everything is dark. Please help me help my baby. Thank you.
