Parents talking about getting a dog

Okay I know this is so fucking stupid but I'm so upset. I dont like dogs. My entire family knows i dont like dogs. Ive told my parents before how I really dont want them to get a dog. Now im sitting in the living room and i can hear my parents, brother and sister talking about getting a dog. They sound serious this time tho - like talking about vet insurance or smt and rules and where to keep it. And im so upset. I really dont like dogs. Its not a fear. Its not an allergy. Idk why i dont like them either. Im just really not a dog person - or a pet person. And im dreading it. If they get it I'll be so upset. And i know its pathetic and stupid but a part of me is seeing this as a sign, since i dont want to be here anymore so it would be convenient if i died - no more people complaining about getting a dog. I know how dramatic and stupid that sounds. Its just how i feel. I hate it
