Hi Patchwork,
I'm sorry to hear about your shortness of breath. That's unfortunate and very hard to live with! My husband has lung cancer and often has shortness of breath. He has inhalers and a nebulizer machine with medicine that helps a lot. You might want to talk to your doctor about prescribing those kinds of things for you.

You also might want to consider home oxygen. Be aware that home oxygen can be very expensive; $2000 to $4000 to buy a new machine or $200 to rent it. However, we found a cheaper home oxygen that doesn't require a doctor's authorization. It only cost $189 which fit our budget better. We haven't had it delivered yet so I can't tell you if it's worth it but I'm hoping it's an answer to our prayers. We ordered the oxygen machine from a company called Osito. You can do a Google search for it.

Another thing that helps shortness of breath is drinking lots of water. When you get dehydrated you get short of breath. My husband drinks a lot of water and it helps him a lot.

It also helps to pray and leave everything up to God. He's always there for you. You just have to ask.
I'll say a prayer for you.
Best of luck!
