Hi I'm Josh. I'm raising money for a new Portable Oxygen Concentrater. My previous device has stopped working and cannot be fixed due to age. I had a double lung transplant 5 years ago, and they have begun to shut down again. I'm in need of Portable Oxygen now, so that I can keep being social and have somewhat of a life. Any assistance would be greatly appreciated, the Portable machine is very expensive. Hence why I'm asking for assistance in purchasing 1. Thankyou in advance for donating any funds.
