Did I get spiked or am I overreacting?

Hi everyone last night I experienced some weird shit and I am still confused so I wanted to know someone else’s opinion.

I want to start by prefacing that this was not my first time drinking, I have been drinking alcohol since I was 16 and I have a good understanding on my limits. Last night, I went to a halloween party with a couple buddies and before leaving for the party I drank one beatbox and half a shooter of fireball. I drank this in a span of an hour and then I felt the usual slight buzz feeling upon entering the party. All was well, I was hanging out and talking normally and I felt fine. I was NOT drunk and did not plan to get very drunk due to being in the unfamiliar setting. About 30 minutes into the party, I needed to go to the bathroom but the main bathroom was occupied. My guy friend I was with knew one of the brothers of the frat and said I could go downstairs to the bathroom. I went down with 2 friends and the frat guy and before we went to the bathroom he offered me and my male friend a drink of this strange jungle juice concoction in a cooler. I know I shouldn’t have drank it because it looked suspicious as is but I was stupid and thought that since my male friend (who is roommate’s with frat guy) was confidently drinking it then I was fine. I KNOW this was not a good way to think about it and this was stupid but I did it. I drank about 5 SMALL SIPS of the drink then put it down and did not touch it afterwards because it did not taste very good. (This was the only thing I drank at the party). Then I believe 20-25 minutes later, I started to feel extremely anxious and it was hard to breath. I was not becoming anxious over the thought of me drinking the punch drink, I just started to freak the hell out. I ran outside and hid behind a car with my other two friends I came with and they said I was mumbling a lot of shit, and breathing very hard and fast. I told them we needed to leave so we left and went to Waffle house and upon arrival, I ran out of the car and hid behind a dumpster and continued to spazz out. I could not speak clearly to my friends who were talking to me even though in my head I knew what to say to them. (According to my friends) I was dropping my head and then would tilt my head back and look at everyone super wide and try to say something but could not. I could not throw up or anything aswell. I was crying and yadada and they decided to take me to the fire station. There, they asked me what day it was and I did not know it but I knew my name when they asked. My friends then took me to the hospital because the firefighters suggested it to be safe. At the hospital, they tested me for fent, coke, and other date rape drugs? and it all came back negative. This is the part that confuses me because if it was not spiked- how did I become so weird like this? I felt like I had no control over my body and I was very numb everywhere as well until they gave me some saline. My alcohol level was at 183 and the doctor called me a “rookie”.

Today I feel more clear headed and I can remember being at the party but not everything clearly after honestly drinking the punch drink. Majority of my events are being told through my friends perspectives because it is all a little fuzzy. But, I did not black out and pass out or anything like I do remember some shit. Anyway, I am just now very confused on what happened to me. The doctors said that they did not know what was wrong with me and gave me an AA paper and sent us on the way after the IV was done. I have never felt like this in my entire life and I have gotten pretty wasted before. I do not drink every single day, it is more like a every other weekend but in high school me and my friends would get plastered on the weekends. So, I have experienced being very drunk after rounds of shots and several mixed drinks and I know how that feels- and these feelings last night did not feel like normal. I really did not drink that much compared to what I normally will drink. Anyway, I am just looking for some understanding on what might have happened and I know it is hard to judge through a reddit post but just anything would make me feel kind of better because I am very curious as to what happened.
