To believe again

Sometimes believing in somethings might left you disappointed in future. I experienced it. It hurts. I slowly started to not to believe in things, even GOD. I slowly turned into a cynical person. Always second guess at everything. When shit are about to hit me, I let it be, like I don't even care anymore. I don't even care about anything.
I still admit that there is good in me, but I'm just tired. Tired of everything. This so called last semester might not be my last semester. Maybe experienced too much disappointment had left me crippled, mentally and emotionally. I missed being the old, younger me. Full of positive emotions. But now, I don't know who or what am I. I'm human obviously but what kind of human. Good or bad? I have no idea.
