Yes, very much sympathy, as has been said.
I haven't had drains, but I have had a long brush with Pneumonia (took them a year to diagnose...) on top of being long-term Asthmatic, so I can empathize with the shortness of breath thing.
Unpleasant, at best...
Target acquisition is always fun, and ticking off long-wished-for wants is a boost.
As long as you can stay cheerful, that should help - but not easy on occasion, as you observe.
Keep smiling, even when you don't feel like it - it really messes with Murphy.
