Hi Dardy and welcome to the board. We're all scared when we're told we have COPD and packed off home with an inhaler and little information. The fear comes from not knowing anything about COPD in the first place.
I was scared for well over a year, until I found this site. Now, I know I understand what it is and how to keep as well as I can, I'm no longer terrified.
You don't know much about your own COPD yet , such as, what level you are, but when you do, you can start getting on top of it. The fear can actually make you feel more breathless and much worse than you actually are.
Type 'Just diagnosed' or simply 'Scared' into the search bar and read a few post from people like you when they first came on here and you will soon see, it isn't as bad as you imagine.
Yes, there are some very sick people on here, but there are a lot who have had it for 20/30 years and are still here and enjoying life, so you see, worrying about not seeing your grandchildren grow up could be pointless.
Well done for stopping smoking. That's the most important thing to do and the hardest.
Your job could be a problem, unless you can get some sort of mask, you need to discuss it with your doctor.
Any questions at all, ask on here because the people on here are very knowledgeable.
You'll soon feel on top of things and in no time, you will be helping other newbies to learn they can get on top of it too.
