Feeling very sorry for myself at present which you all may feel is very selfish. I apologise in advance but I am finding it very difficult to come to terms with this crippling COPD. I think if I am being honest I find it very embarrassing having to use oxygen in public. My sats on exertion are dropping dangerously low to 76! without oxygen ( I have just tested myself with my oximeter with 2% oxygen walking in my home from my kitchen through to lounge and extension which is a few yards there and back and can see sats dropping until I rest. I need to discuss it with my respiratory nurse again as I was adamant I would not carry a bottle around. Surely there must be another way? The current ambulatory machine is not adequate apparently, which although feel embarrassed about doesn't seem so obvious, apart from when a young lad in the supermarket said "why has that lady got tubes up her nose?" Felt awful. Am I too sensitive. Also I am finding I am crying inappropriately (I feel anyway) although have lost my lovely cocker spaniel Bobby last week and my son has got a new house, its probably empty nest syndrome but I still feel emotional and useless any advice?
