Feel like dying..

This will be my second time here, the other one was all about school and now it's about my health. A few days ago I have experienced a pain in my throat (specifically at the lower part of my adam's apple). I have some assumptions that it is this what they soo called "GOITER", but I can't confirm it because I am really afraid to see a doctor. I am now in the final year of my college studies so I need to double time, I lack sleep and cannot even eat on time. From the day I've felt the pain I can't help on thinking that I will be dead sooner or later and it makes me down and frustrated. I really got a problem with overthinking. I haven't told my family too because I really don't want them to worry. What to do. Am I gonna be dead? Can this wait until I graduate? I know this is nonsense but I really need your opinion readers.. Thank you.

Hello Sheen.

Research iodine, there is lots of information online and ut requires thorough investigation to know whether it will suit your body before trying it.

Thank you..
