Last night.

So yesterday me and my boyfriend got a lot of money and bought around 200$ worth of cocaine...i wouldn't call myself an addict because i can kick the habit very easily if i want to. my boyfriend is not so lucky..but he took me home after we did all of the coke and my throat was in so much pain i couldn't even breathe... so i drank a lot of cold medicine and drank tea and it got better as time went on...but just as i was about to go to sleep around 10 pm...thats when i started to panic. my heart rate was very irregular and fast..i was FREEEZING but my head was 1,000 degrees. my stomach started hurting and i thought i was going to throw up but i never did..i tossed and turned all night, debating calling an ambulance. i knew i had gone over board, i started to panic thinking my boyfriend had done more than me and was probably doing more as i thought that and didn't have a phone...i was worried he was overdosing as was i...i still haven't heard from him but im sure he is fine. i didn't sleep at all and my whole body is sore from shaking violently all night...i need advice? help? my parents would kill me if they knew i was doing coke again...i need remedies? something to keep me calm if i go over board again?...help?
