First Trip (horrible yet non regreting?)

a had takin a half of an eigth over my friends house with 4 other people and 2 sober people to watch out for us. It started out as a instense stone i felt like i could not move and felt like i wasnt actually there. We started at 6. We decided to close the lights and watch the movie the laybrith wich i thought was scary and started my bad trip. I also reilzed i needed to leave in a little bit so i freaked out beacuse i couldnt act normal or feel normal at all I was scared freaking out and I went to the bathroom and threw up like 3 times it was horrible i didnt know what too do i felt like i was stuck in the shroom world and coudnt controll myself or leave
