Is this because of hormonal disparity?

this is what happens:
i drink some coffee or an engery drink
after i get kinda dizzy, and i HAVE to sit down, i can't pace
i see red&green spots and this lasts for something like 1-3 mis. after i get them i find really emotional, and cut myself
i started have these about 2 months after i have my first period. i would own them 1-3 times a week, and now i am have 1 or 2 everyday. i get them more when i drink caffin and during my time.
i am 13 and weigh 115 pounds
what is this? is it because of hormonal imbalance LOL u cut ur self thats ok though it happen to me sometimes i just try to hold going only happen at home not a school probally beacuse i enjoy no caffine at school but at home i carry one after a long period playing on the computer and i stand up and it's resembling im drunk i cant walk and everything turns red and blue and i procure dizzy but mine last for lone 5 seconds at a time so i cut down on caffine and drink some really moral tea.
