I'm shaking and terrified

Every night I'm shaking and I'm feeling like I'm already, my hands and legs go numb

Doctors said that it's because I have low blood count but I think it's the effect of my psychology condition as I am traumatized by my past and I'm over reacting sometimes,i want someone to hear me and to take care of but I don't know how? And why and when would I get helped?

My teachers tell me to stay focused on studies but I'm shaking everyday I simply can't focus on a 15min YouTube video constantly,i know I'm terrific and i hate myself now, i wish someone could help me to break this wall, i want someone to take care of it because I'm tired of trying everything everyday....
