I'm doing my second yr in PG degree. I don't know why I feels like saturated. You know... like kind of don't want anything anymore in this life... not interested in anything at all... just want to go and hide somewhere forever... and maybe i think due to this I'm experiencing frequent mood swings like from extreme happy to extreme anger and sadness... I'm having headache at the back and sides of my head... i think that may be due to the above said reasons.
