Canacookies to much to handle

Ayyy, so i had a really fucked up experience yesterday with cookies, my buddy and I ground up a ton of shake in a coffe grinder and sifted it in with the flour. there was no way to tell how strong they were gonna be. I ate 3 and my buddy ate 3 right off the bat. 20 minutes in and i was already starting to feel high. I got really really high very fast. and out of nowhere my stomach turned and i started throwing up. i threw up about 10 times and by this point i was to high to even function. Everything was different i felt as though i had taken intense hallucinogens. I than got hit with a severe panic attack and my heart was going probably 160 beats a minute. Throughout the night i was delusional, i was slurring my words and really really fucked up, still puking here and there. my puking was done by 10, and i had aten the cookies at 420! my heart was stll super fucked up and i was worried about having a heart attack or if i have? i had many symptoms of one but am not sure. today i woke up and my heart feels somewhat soar today like it went through alot. i would like to know what people think. i am worried how much pressure went through my heart aand if i did have a heart attack and not no it? i was puking, could barely walk. and pretty much to fucking high to tell the ceiling to the floor. and i still feel very wierd today as if i lost a bit to many brain cells last night. i remember before i passed out from a pill given to calm me down. tripping out about my situation. i was convinced i was gunna be vegetable the rest of my life. some fucked up cookies i gutta say!

yes very rookie mistake, as i had no idea how high i could actually get, the high was not just in my body but in my mind. im just worried about my heart is all, it still feels weird, but i may just be trippin out. you think if your heart was going top notch for 10 hours it may have some bad effect on it. i think i may still be a bit high swell. yesterday after taking them i slept about 15 hours and was very zoned out. even today i am feeling groggy and zoned out. what else i don't get is my friend had 3 cookies and all he did was get really high and pass out with no after effects? :S ide also like to see what people think, if i should go see my doctor about my heart
