EMOTIONS-What a waste?

To be honest, i really don't know what i want to write, my mind now is totally blank.... I am lost...since a couple of days .... Well, why? That is one that you don't need to know (No I ain't being rude).... But my mood changed from excited to moody....
I went to work today with a serious face all the workers kept asking me why so serious or why so quite why so depressed what happened and i ofcourse replied definitely a smile. Professional eh? I don't know what should i do now I mean I really don't know what had wrong had i done that i deserved all this I thought i had done all i could to,...........but in the end, it backfired!!!!! I really am speechless. Now should i be stubborn? And if i do, is that a selfish act? Or should i just let it be.... i really don't know..... I need to learn to be tougher.... i had been very weak ever since this year.....tears keep coming down easily.... I hate myself.... How it even turned into this situation...the whole scenario..... i am not really sure, I am BLUR!!!! BLUR!!!! B...LLLL...UUU....RRR....
