Help Nathalie in her fight against breast cancer.

I'm not sure how to even start this, but I need some help. It's hard asking for help, but stage 4 breast cancer is a monster and the costs are astronomical. I'm struggling. I don't know how much I need, but any amount will help and would be truly greatly appreciated. I just can't do it on my own. If you can’t help, please share. Thank you.
