I was born as a very sensitive, I studied very deeply but now I'm full of negativity and loss all of my brainpower...

There have been studies that have shown that too many traumatic life experiences can actually cause a person to loose their empathy, and also cause brain damage to a certain extent.

You are at the age where that often happens. It happened to me as well. I realized I needed something that not only paid but helped people as well. I discovered when y ou help someone in need it actually helps your own growth, satisfaction, and a re-discovery of dreams I'd forgotten.
