Possible std???

Hey guys so I don’t have sex and the last time I used a vibrator was two weeks ago and I only use it over my pants…a few days ago my vagina felt weird and then the next day it burned a little when I peed and today it hurt when I sat down, walked and bent over. Then when I went to the bathroom to pee it burned SO BAD I shed a few tears. I checked to see what was going on in there and the inner lips were pink, there was white stuff all around and it didn’t have a pleasant smell. I know that it’s probably an std but I’ve never had one before and I’m really freaking out. Not only because I’m in so much pain but because my parents are very taboo about this sort of stuff. I’ll have to tell them eventually but someone please help me figure this out!!
