Went into shock, no EpiPen experience

I was wondering if anyone has went into shock without having their EpiPen. If you can, please share your experience and how it effected you. In my experience I ended up going into a shock at a restaurant and went straight to the bathroom to try to gain my composure. During this time I was still new to having a food allergy, my first attack was just hives and mild swallow airways. The time u went into shock was my 2nd reaction ever, I didn’t even know what I was allergic to at this point (sesame). Long story short, I ended up passing out in the bathroom of the restaurant and later woke up. I don’t believe I passed out for that long, maybe a few minutes at the most. After I woke up all of my symptoms were gone, I was just really tired. Didn’t go to the hospital just went home after. Has anyone else experienced something similar ?
