Symptoms, what's wrong with me?

I don’t want to go to the doctors over something little, so I decided to look up the symtoms online and I didnt get anything. My friend is hounding me to go to Urgent Care but I dont think I need to right now

1)for the past month I’ve felt like I wanted to puke everyday day and I get blooody noses a lot but I think thats from the weather, also headaches all the time

2. couple of nights ago I got this taste in my mouth like of metal like I was eating a metal spoon

3)later that night I got like a burning feeling in my lower throat of like acid burning, and when I first start to eat it hurts so bad that I didnt even want to eat, so far it only seems to do it with hot food so who knows

4. then I coughed up black stuff and bout 10 mins later it was thick bloody sh&t(but I dont knoow if it was from possible the bloody nose I had 25 mins before that)

5)then today I woke up and the burning feeling is in my chest too but it feels like I swallowed icy hott kinda burning

I told my mom bout it, she told me “I dont know what you want me to do about it”
