Am i being the "badguy"?

i am 12 years old and i play softball. at my games today everyone smoked. i am allergic to it but there is really nothing i can do. my mom does not smoke but when she got home her jacket smelt bad from the game. i asked her kindly to take it off, she got annoyed and said she was cold. i scooted away on the couch. a little while later she asked if i could come see something on the computer, i went over. my throat hurt really bad as if it was closing up and i was repedidly coughing. i was like take off the coat. she got sooooo mad as if i offended her. then she was like bit** am i over reacting or should i b mad
