I am lost :(

In CHD I spent 4 yrs and this was the place where I got my first crush. and with this question I hope CHD peeps will help me to rejuvenate my life. I was not like this before, I was cool , ranker, competitive ... got great marks and also got the highest placement in my college with a package of 17 CTC in IT sector. My life was set but then here comes the evil chinese lady manager from USA. She changed my timings t0 2 pm to 10 pm,, my social life was fucked.. I was not loving my work and got so frustrated that I cut off my friends but lately my performance was bad and they laid off me .. its been 8 months but the pain, the guilt never fade a way.. now I am preparing for govt. exam and MBA.. but reality is I don't know my pain the void will ever be fulfilled by something? I have no interest in living.. my age 23 M BE graduate
