Please help me to help myself

I am Diana and I have stage 4 triple negative breast cancer.
I am a Mother to Jack (3) and Ella (21 months). I want to see them grow up. They need me as their mother.
Please help me to fulfil my only dream. Conventional medicine is trying to prolong my life. I am trying to save it.
I want to also try some natural therapies and alternative alongside. I am struggling to even eat healthy financially. This is a cold hard fact of cancer.
Please help me to help myself.
