Sick 😩😩

What are your remedies to get rid of a cold/possible bronchitis?! My nose is so plugged I can’t breathe 😩 I’ve applied Vick’s and even tried peppermint oil (young living) and this mucous is not budging. I feel like I’m dying idk what else to do. I feel like I’ve tried it all. I take vitamin C and elderberry, I already take vitamin D every day and I’ve even drank pineapple juice (carefully of course) to help with my nasty cough along with hot tea and honey. Helppppp!
