I Feel Energy In My Fingers

I am fairly new with all of this, so please excuse my rookieness.

About a year ago, I've been feeling this weird feeling in my fingers when I focus on absorbing something in the space around my fingers. When I do that, my fingers go really tingly, and my hand starts shaking. It feels like there is energy running through my hand. I have only tried this while keeping one of my hands closed, like I am holding an invisibe object. When I open my fingers and focus on sending energy somewhere, the feeling disappears. I've read about chakras, and have tried to send energy to the chakra in the top of my head (not sure how it's called), and I've been feeling more energetic and being able to think more clearly. Can someone help me find out what is happening? Is there the possibility that it is a medical issue?

Also, I've read stories about telekineses, pyrokineses, cryokineses and being able to control the weather, all starting with this feeling, but I have not noticed anything like those four. I wish it was, because I'm a great fan of the X-Men series.

I'm not sure if any persobal details are needed to make a conclusion, but I am only 13 years old. Also, after a while, my fingers feel so full of energy I can't go on, but the more I practise, the more energy I can store. I read about supplies of psychic energy, and I might think by practising I can make them bigger, also it seems that when I'm tired and I jump in a pool, I feel energy again. I'm not sure if that is relevant though.

Thanks for helping
