Bronchitis or something else ?

Ok last week I started getting chest pressure , feeling unlike myself a bit a little tired but I still didn’t know what the cause was a little backstory , I sleep with my window wide open and a fan on because my room is hot when I go to sleep and the temp usually drops to 50/40 degrees , the day I started feeling ill I had to walk 5 miles in the wind it was very cold then I drunk coffee which made me jittery , and I had a panic attack and my ears were ringing and I felt TERRIBLE (I usually don’t indulge in coffee so that’s why ) but honestly I really think that’s unrelated now because it’s been almost two weeks just wanted to mention it because I did have my window wide open and my fan on to calm myself down . Fast forward now , a few days ago I was dehydrated had body aches I had a low fever shivers a headache lost my appetite and all I wanted to do was lay down and sleep my life away y’all it was terrible , now I feel ok I wouldn’t say like great but I’m still coughing like crazy , sneezing and my chest pressure comes and goes and I’ve coughed myself into shoulder blade pain and chest pain and my chest (lungs ) feel spongey when I breathe in or lay down but that’s because of the coughing that I know . And my throats a little sore

I’ve taken mucinex which has helped so much . Anyway don’t wanna make this too long so is this a chest cold , bronchitis or what ? I have an idea I’m just confused as hell I’m sister shook
