I feel not many people are aware of the Pulmonary Fibrosis Trust and the help and support that they offer people with this disease. I contacted the trustees via their site pulmonaryfibrosistrust.org and they agreed to purchase a portable concentrator for me. So that I am able to return to work. I would recommend anyone who needs help to contact them, or to make a donation.
A very big thank you to Peter and the other trustees for all their help.
