Basically, I was trying to microwave a potato last night, and when I microwaved it, I accidentally set it for ten minutes, and left it there for said ten minutes. When I smelled smoke, I came out and opened the door to the microwave. After doing that, smoke went right into my face, and started to go all over the house. It smelled bad, and I was coughing. I didn't air the house out, the smoke just kind of dissipated from the air after about thirty minutes/an hour. I instantly started panicking. I had a bit of chest pain and of course a cough, but it went away last night. I did not eat the potato, either. It was absolutely charred. The microwave was fine though, I used it a bit ago, and it is working fine, just smells like smoke. 

This morning, I woke up again, and it is back. I have very little chest pain, but a frequent cough. It still smells like smoke a bit in the area where the smoke was. I am afraid smoke might still be in the air. I am also afraid not airing the smoke out was an issue. I am mainly afraid I will die soon, in hours to days, or that I will develop heart disease or lung cancer. I still have an urge to cough as I write this. Everything else is normal, though. 

I was excited for this weekend, but now it is ruined. I am afraid I will not even make it to Friday! Once again, I am paranoid I am going to die of a health issue.
