Charlie Bird has revealed he feels "so upset and guilty" for not being able to respond to the hundreds of letters of support he receives every day.
The veteran RTE journalist said it "hurts" him that he doesn't have the "time and the energy" to send individual responses while he battles Motor Neurone Disease.
Charlie has consistently thanked people for their kind messages of support he has received over the last few months saying it has helped him cope with his diagnosis.
