Hi, Worried With Questions. (seizure?)

I think i'm having seizures, or i'm just calling it that until I can confirm what it is.


Background:
seizure 1: I was about 10 years old, riding in the car with my mom and lost vision and felt like I was going into convulsions. It also felt like I was urinating on myself. I had just eaten a meatball sub from subway.

Seizure 2: i'm not sure how long after this one happened, but it was within a year. I was in school, sat down for lunch, blacked out and went into convulsions again. This time, I noticed I could still hear everything, just couldn't see. I went to the doctor after school, they did various scans but I wasn't diagnosed with anything. I couldn't go immediately because the teacher wouldn't let me call home. She said it was probably because of blood sugar and made me come back to class. I had just sat down to eat lunch when it happened, but had maybe only had a few spoons of green beans.


Seizure 3: fast forward about 8-9 years after not having one at alland i'm sitting in my bedroom, just ate 2 bowls of cereal for breakfast(frosted miniwheats), got a very heavy feeling on my chest and I remembered this from when I was a kid. I made it to my bed and the same thing happened..Vision loss, shaking, but could still hear.


Okay, go forward about another year to today and I had another about 1 hour ago. For about 30 minutes before it happened, I kept getting this constant urge to pee. I kept trying, but very little would come out and it would burn when trying..This probably happened about 3 times. I went back to try again, but this time I just sat down and waited for a few..The same tightening of my chest occured and I fell onto the floor. I remained pretty concious but the convulsions seemed strong and it seems like I could talk to myself, telling myself I have to stop doing shaking. When it finally stopped, I had drooled all over myself and I was a little confused. Today, what i've had for food was more frosted mini wheats for breakfast about 12-13 hours ago and orange chicken with rice and broccoli for dinner.

I know I should go to the hospital, but I have no insurance and this one didn't seem any worse than before, but with the addition of the urge to urinate before it happened. I have felt fine all day which is what's so weird.


I'm 20 years old, male and in pretty good shape. I'm sure many different things can cause something like this, but if this sounds familiar to you, please share. I'm currently taking a medicine called hydroxyzine, but only for a few months now.


Thank you
