Help for my dad

In 2015, my dad was diagonsed with bone and blood cancer. He has fought for 4 years and unfournately, they are struggling to pay for everything at the moment because my mom is the only one working. We have alot of other personal issues but that will be up to my dad to tell the people he would like to tell. If you can help that would be awesome. Theyre truly struggling and every penny goes to his meds, food and whatever else they need. Anything helps.
