Anxiety - I've lost my job?

I suffer from severe anxiety disorder and yesterday I was made redundant fom my job and I feel like i'm loosing the plot. I am a single mum and I have a Mortgage to pay. My head is all over the place and I feel really strange (like i'm not here). I've been in my job for 12 years and I gave up alcohol 3 years ago. They are expecting us to carry on as normal at work for another 30 days until the consultation period is over but I seriously can't do it. Its freaked me out and I can't deal with it.
