bought an oxygen tank + nebuliser!!

my doctor was very nice despite the fact i waited there for like 2 hours lol, she recommended that i should buy a nebuliser. i'm not unfamiliar with that, as it was what they gave me when I went to the ER back in May; only difference is it's a portable one, so I told my parents abt it. They bought me one the next day and I just have been using it mainly at night (as it requires me to sit in my bed for 30+ minutes and it does make me sleepy), but I see some improvements! my lungs do ache because they're pretty much bruised lol, but I'm able to sleep more comfortably now, so im glad. My oxygen tank is also a good top-up for extra oxygen I can breathe in when I need it (it's abt 10 litres or so), so I think i'll be okay y'all.
