Worse Pain Ever

So I was fine for the entire morning until about 11.40am. I was at work and my shift finishes at 12, I suddenly felt hot and cold and started to shake a little. At this point I just wanted time to hurry up, so I could go home and heal up. Next thing I felt like throwing up and needed the loo. I went to the toilet and came out feeling no change. I still felt ill. Time seemed to be going so slow and I still had 15 minutes to go, I felt really bad and was considering to ask my manager if I could leave early but I figured i might have well waited it out. But even within the last 10 minutes I couldn't pretend I was fine. I threw up and couldn't cope with this feeling inside of me. The last 5 minutes I decided to go to the toilet because I was shaking too much and I couldn't physically work. It felt bad. As it hit 12pm, I dashed out. I approached my bus stop and saw that there was a bus and that there was no way I could have made it. So I had to wait. It was a painful wait. I waited and waited whilst feeling what I can only described as death! I even considered dropping on the floor so someone could call an ambulance, I just wanted the pain to end. After a short but what felt like a lifetime wait, my bus came. I sat at the back and felt so ill but was just glad I was finally closer to home. The bus seemed to be slower than usual and every bus stop had passengers! I felt that there were people on the bus staring at me, because at this point i wasnt looking great and I really couldn't care less about how I looked. My eyes were revolving and I was telling myself I could make it home without causing a big scene. When I finally approached home, I could feel my legs getting weak, I couldn't walk with strength and was dragging my feet. I got to my door and knocked. My mum opened the door and asked why didn't I bring keys. I couldn't hide the fact I was feeling ill and usually would if it wasn't a big deal because she's a worrier. So as I stepped into the house, I ran to the toilet to throw up nothing but saliva and air. My stomach hurt along with the pain on my left side of the rib. I got changed and just jumped into bed. My hands and feet were pale and frozen. I was shaking quite violently and couldn't control it. My mum made me some ginger, egg and chicken soup. And I was under 3 duvets and still felt cold!! There was something seriously wrong and I felt like I was going to die. Afterwards, I fell asleep and my mum left for work. When I got up, I didn't feel so bad. In fact I only had a slight headache. I had no idea what the hell that episode was but I never want to experience that again!!
