I feel like an asshole for this

Theres this girl in my bio class who acts like everything triggers her- like shell be like “omg dont talk abt natural disasters it triggers me” “dont talk abt snakes they scare me and it triggers me” and it makes me SO mad and i keep thinking what if i “accidentally” have my sleeve roll up and have her see my scars (theyre all fully healed and old) to see her reaction and im NOT gonna do that and the fact i keep thinking it disgusts me.
