Heaviness

My brain is heavy, I cant sleep, I think too much information tonight.
A lot things happened tonight.
And I need a long time to type it down, and now is not a good time..
I am having headache, this type of insomnia only occurred when I was in secaondary school, that I stayed up and this is the consequences...
I thought I had adapted to sleep late, and seem now I getting older, and my body just can not afford it...
