i know how u feel...i suffer from the same problem...
sometimes i just feel like sleeping for hours...
I know... I don't know how people do it... Sleeping less hours... I wanted to do something different... Not go to a standard software job and do something more... but during the exams everything shattered: My confidence, my pride ... I started doubting my own capability...
Now after some days I'm back to my old self... but it still pains me that I didn't do well because of some health problem. .. .
