Portable oxigen machine Campaign

Good day my name Sharnelle Kruger. I am on a oxygen machine for 16 hours a day at home. The reason for this is so that I can get money for a portable oxygen machine that I can use for when I want to leave my home. So that I can go the the shops and do activities outside of my house. The reason for the oxygen is because my oxygen levels in my body is low, the reason there for is because my hart and lungs are damaged. I am asking for the help of you guys so that my life can be a bit easier. Thank you
