Stress..

Im so stressed at work recently, I dont know how long more I can take it..im dropping so many balls at work that its not even funny anymore..

I have everyone chasing me for stuff and im not able to reply in time or look carefully at emails or issues. .I can only touch and go and no time to follow up on the status of all my moves. .I feel like everyone is unhappy with me and I just feel so frustrated..I really feel so lousy abt myself sometimes urggh!! What shd I do??? God are u there??
