I Just took ecstasy... i feel very strange?

my heart it racing, it's like i can feel my blood pumping through every inch of my body, I'm rolled twice before, but never to this extent. I took one tab tonight, thinking it would just give me a little energy at around 12:30, my entire body feels strange, like its pulsating or something yet I don't want to move around, every time I move I sort of feel sick. I want to make myself throw up, but I don't know if I should throw up or just ride it out? i also feel a sense of like paranoia. I'm sitting in my bedroom and every sound or light or shadow stands out to me
