Like i get grossed out by almost anything, from dust on the ground to an earring, it just grosses me out and makes me wanna throw up.
You have a sensative stomach and little things can be a trigger. I have a friend who is just like that. One time we were walking and i showed her a picture of something and she started puking. I was like TF??? Many people have it.
Maybe its just because you over think things. When i found out what was in dust, i became sooooo freaked out. I still am. Just dont over think everything and you should be ok.
