What's the point???

What is the point of working so hard? When you know you can't get what you deserved to receive? Tell me. I don't get it, why?

Am I dumb? Is my brain actually deteriorating? Or I really don't deserve what I worked so hard for? Tell me. I don't get it still.

Why?!?!?!? I hate being and feeling like this. It sucks, big time.
