When everyone I know breathes, their stomach moves in and out, when I do that I feel uncomfortable, and sometimes it's painful to expand my stomach. I breathe raising my chest while none of my friends do. I also have problems breathing through my mouth, it'll cause my teeth to feel sore and it's just...weird.
I also have trouble that sometimes, I can't breathe at all, my whole chest will become painful if it moves a tiny bit, I find it strange when none of my friends have that problem.

Although it might sound silly, lots of people don't breath correctly. I know that breathing incorrectly (eg. using the wrong muscles to breath) is dangerous, and cause back problems and many other issues. A physiotherapist can you help you if this is your problem. However, I don't think this explains the feeling in your teeth or the pain in your lungs.
There would be other conditions that I do not know about, and you should see a doctor to have them either ruled out or diagnosed and treated.
Nonetheless, you should probably see someone.
