i hate everything

I am already in college now and I found a lot of new friends its like a whole new world again. I love studying Psychology but the subject units that I have to earned is wearing me off, I am drained and tired, sometimes I ask myself, what shit matter today, does it matter in the future? what if im doing all of my best here and in the future I took a different path. I am a scholary granted student and yet I couldn't find the drive to pass this degree, I feel tired in every part of my body, I feel empty and keep longing for someone's embrace or any comfort and yet no one could fill it, what am I doing with my life. What's my purpose, why am I here just to feel every uncomforting reality.
