coke is also a stimulant, you were speedin out of your mind, your heart was jumping about, then, when combined with the powerful, maybe sedative effects of the marijuana and alchohol mix, you were losing control of what your body wanted to do and what you were trying to tell yourself to do, You had no more connection with any part of your body,
times like this are more often than not, not the best time, i would stick to one drug for a while, or maybe none, considering it doesn't sound like you're handling yourself very well
wish you the best
