Money For Animal Shelter/Cancer Patient Donations

I am Camille. I have always wanted to donate to cancer patients and animal shelters, but I have no money to do so. Last year was tough for me and I had to spend all of my savings to keep myself from being homeless and starving. But there are way worse things than that, so my goal is to donate all the received money to animal shelters and cancer patients and make them at least a bit happier and healthier and raise awareness, especially in my home country, where animal shelters are lacking food and medical supplies, and cancer patients don't get funded enough.

How would I spend the money:

1. Animal Shelters: donate a bit of money, buy needed stuff and food and bring it to them.
2. Cancer Patients: donate via website

Thank you for your generosity, I hope the world will become a better place, because small things work big.
