Frustration.

For godsake, these 2 years I've been doubting myself more and more. I can't picture myself doing this anymore, reading something that I don't even understand, particularly, throughout this 2 and half years ( foundation till now). I've no idea what am i learning, and for fucksake, I'm doing all these for what? Wasting time and money? Maybe I'm just one that hard to learn and hard to concentrate. I've nothing really left when comes to studies. EMPTY. SO FUCKING EMPTY.
