I've developed a sudden productive cough and I know it's gross but I'm coughing.upnloads of green/,,yellow stuff and it tastes gross. My chest feels a little sore and tight. My throat feels dry and scratchy too. I'm panicking that it's pneumonia or something bad. I'm scared to go on sleep. I'm panicking. Do people think probably not that serious and I'll be okay to just see how it is in the morning.i have super bad health anxiety so this is sending me into a spiral.
