What causes the pain

A black day .I made a mistake at work and it cost me more then I can tell you. In my trade there is no room for mistakes it must be perfect every time. And I cancelled 2 jobs that I did not have the materials to comeplete and that is the problem I am resposible to be prepared and cancelling work  is a bad thing.So I may have some action taken towards me including fired. So my depression has been borderline and now I am over the edge.So I am having a full blown attack including shakes and vomiting,hot flashs and chills , crying is the worst part because I go away and hide from the people that might help.May I have the strength to not do any thing that might hurt the ones that love me.
