HELP ME! Tmi-ish alert

I'm really really freaking out! Down there has been feeling a little weird lately. So naturally I took a mirror to check stuff out and it looks like a little brain looking thing slightly poking out of the vagina hole. I am so week stomached I can't move thinking about it. Is something prolapsing? I never had it look like this before! I thought I just have felt dry down there but appearantly it's whatever the crap that is! Please help. Any advice would help!
