angry and upset

Today I am angry and upset.
I didn't get the job I went for yesterday. The interviewer called. Apparently they interviewed people in the order they thought they met criteria etc. I was interviewed first. I was apparently the best candidate on paper. I had the job in the bag until 3pm yesterday when they interviewed a woman who already works in a Supporting People team for a local authority and does some user involvement there. She wowed them at interview and got the job. I am gutted, truely this is worse than missing out by miles. It makes NO SENSE.
Peopel keep telling me oh there will be more jobs and God has a plan - but I am finding it increasingly difficult to see how that can be so when I am SO miserable in my job.
Then a client called and made it worse.
Really really low, all I want to do is take to my bed and stay there.
