Feeling low

I feel very low today, no, have been feeling a low for the past few minutes.Actually,  today began on a jovial note, as always the confusion what to take for lunch. Mom suggesting  something and I wanting some thing else. 

The feeling is not sadness, something more than that. Difficult to name,  it leaves a bad taste, a bitter feeling and creates a negative aura and most importantly no work gets done at a time like this. Also, I try and drop everything I am doing least the result is not up to the mark, that again results in negativity. It is like the domino effect. 

I think it is helplessness over something that I can only watch as a bystander. I shed tears but the feeling refuses to go, I tried working to get over it, I tried talking to people, reading, nothing seems to be working. Hope it wears out soon.

PS 17/12/11: This indescribable feeling was gone by evening though I had to down McDonald's McFlurry(with Oreo), sweet & chocolates really help during  a sad moment.
