please be safe

So this happened to me at bid day parties. I didn't know this site existed but i feel like this is the best place to share. So I am a 2nd year (not in a sorority) but my friends are in one and i still go to frat parties with my friends. like normal people we party hop cuz we have friends in different frats. On the night of bid day we decided to start with Phi Psi, then go to sig ep, aepi etc. We get to phi psi and one of their members that ive seen occasionally gives me a cup of jungle juice while my friends go to the bar (i usually get from the bar too but didnt think it would be a problem). 10 minutes later after drinking just one cup, i start to feel completely drunk and very dizzy and this never happens to me before. my friends come and get me and we uber to the next party but im not feeling myself at all. i couldnt walk, my vision was blurred. at sig ep i completely passed out and my friends took me home. the next day i was confused as to how i got so drunk so fast, and my friend remembered the random guy giving me the drink and they automatically assumed that my drink was spiked. We were in shock cuz we always go to phi psi and stuff like this usually doesnt happen. i want to say it was my fault for getting a drink from a stranger, but at the same time this is wrong! please, all girls who go to phi psi or ANY FRAT in general, please dont trust anyone so easily!! i cant even bear to think what wouldve happened to me if i stayed and if my friend didnt party hop.
