my mom keeps making fun of my phobia.

i don't wanna sound whiny, but im deathly scared of puke and everything around it, called emetophobia. at first, my mom was supportive, but now she just tells me she's nauseous or has a stomachache for fun and as a joke, and then gets mad when i leave because ID RATHER DIE THEN VOMIT. what a surprise ill leave.
