Nothing works

I have dropped MD twice and it always doesnt work right. i had a red apple yesterday (from Melbourne) and i just got really energetic and but nothing else i just ran and then there was the come down nothing fun. One of my friends suggested it cause he took it a week ago and he had a great time audio and visually. a long while back i took some xanax and that also didnt work so i dont know if it is something in my body but its just really annoying
