First Nigghtshift and I had to go home 3 hr early….

I just had my first night shift and it went really bad. At around 2am I was hit with a wave of nausea that didn’t go away for hours. Eventually I also began to get visibly pale and start shaking and sweating. I decided to go home when the room began to spin and I was having trouble speaking. Honestly I couldn’t decide if I was going to throw up or pass out so I went home…

I feel so incredibly embarrassed since this was my first impression on my coworkers. Is this normal or is something wrong??? I’ve never had anything like this happen before.
