Lay Offs At Work

I have been completely a mess the last few days. As the newest person in my department I thought for sure it would be me, but no they hit my boss. And today I find out I get about 2/3 of the accounts he handled added to my already overwhelming work load. The thought of it had me paralized all day, I could not get much done at all. So I ended up with some sort of god awful heart burn all day that had me near tears and racing home to an empty bottle of Rolaids. (G&^*&^*& D&&^% Fat Cat) Resorted to baking soda in water. That is how desperate of a situation it was. I am thankful I still have my job, I am scared to death someone is going to find out I have no clue what I am doing.
