Not so good start...

I do not like the days when i wake up with heavy heart and unknown depression of sorts...i myself do not know why and how i can be depressed on a bright Friday morning. Not really sure what causes it. I just want to go back to sleep. Is it fatigue ? fatigue after 8 hours of sleep ??? Is it even possible ? I don't want to talk to anyone, don't want to listen to anyone. But, that is kind of nearly impossible to do for me....am feeling so depressed that i can go watch the crappiest of senti movie and cry my heart out...OMG ! something is wrong. Looks like i need professional help here :(
