Oh... I'm so sorry to hear about your health :(

I also have them. Emphysema :( It sucks and is pretty scary these days. Especially with COVID etc.

I've used Vipassana and changed my breathing patterns to accommodate the lower lung capacity. Breathing deeply and fully into my lower lungs.

There is special training to learn to do this.

I also try to stay calm these days. Stress impacts the lungs directly. So...

It's tough. Dealing with illness every day.

Sending warmth and health. I'll follow along anyway and hope you heal...
