My vagina burns! HELP!!!!!!!!!!!!!!!!!!!!!!?

My vagina hurts/burns pretty bad right now. It's really sensitive. I was *face-palm* masturbating earlier and i stuck a *another face-palm* toothbrush up there. I cleaned it before hand. It was pretty intense then I used my fingers. This was like my first time doing it. And it's super sensitive and it burns to pee. HELP!!!! I'm having a panic attack!
