Hi everyone, I (34m) have stage 4 cancer and lately it has been causing me to have liquid surround my lungs. I have a drain that I can drain the fluid daily but sometimes when I get worked up I get extremely anxious and almost pass out from not being able to breathe even though my pulseox is in the 90’s. Does anyone have any quick breathing or quick exercises I can do once I start getting worked up? Also, if I took Xanax regularly so you think that would help? 

Any help would be greatly appreciated :)
