Abdominal Pain, Ringing Ears, Numbness In Body, Increased Heartbeat. What Happened?

So, I do not know what just happened to me. I have been having severe abdominal pain for about a half hour before the incident. The pain started with just movement. I thought maybe it was because I had to use the bathroom but i didn't. Then a ringing started in my ears. And my eyesight began to be crowded with what seemed like bright flashing lights. I could really see. The ringing in my ears got louder. My who;e body felt numb and heavy. I tried lifting my arms and they felt heavy to lift. My head started pounding, but didn't hurrt. Was just like blood pumping. I decided to try and lay down on the bathroom floor and see if it would pass. I couldn't hear anything but ringing, see anything but the spots of light, or feel anything. Also could hear the blood pumping in my head. Within a few minutes I opened my eyes and could see. I got up slowly and felt disoriented, but the abdominal pain was gone and the ear ringing. What happened to me?
