Am i crazy or just weird?

maybe im insane, but i lost my job in july and at first i didn't take it too hard, and i decided by september ill start looking again but i don't know whats wrong with me, i can't look because i get depressed that i'll never get a job again and end up with no money. and i get so scared of the rejection that just the tought of applying for a job terrifies me to the point of throwing up and panicking, what is this?? and how can i stop myself coz its so annoying, one minute im positive about all then im depressed.
