when does it get better

i'm 22 i'm still young. i hope i don't sound dramatic but i'm soo scared. i hate seeing guys my age being healthy. i'm soo tired of feeling out of breath. tried all kinds of medicine and none have helped me. i miss not having it. got diagnosed 3 months ago. i have no one to talk to about it not even my family. i can't believe being young and stupid and trying to fit in with people by vaping caused this hell on me, i miss not having it, i miss being healthy soo much it's insane.
