A BIG spider (about 3 in total) and babies are in my bathroom and im hypervenylating. what do i do?

i walked in this morning and there were like a million spider babies all over the floor so i got my mom and she told me to stop acting like a baby so i tried to ignore it. then i wanted them to be gone already so i wouldnt be scared to go in there. i got some hairspray and killed 3. then i got Off! spray and started spraying all of them (they were all towards one area towards the bathtub) and i look to the side and the mother comes at me slowly about a foot away and is HUGEE it looks sortof hairy (not that much), brown, and including legs about 3 inches all around so i panicked and ran to the other side of the house dropping my stuff. i have been pacing back and forth in the same place on the other side cuz my parents dont know about the really big mother spider. i started hypervenylating and crying for approximately an hour and i wont leave that spot. what the heck am i supposed to do now?!?
