The confused things

Recently, I am have been in a state of deep depression on account of losing my job. I have been almost a month without work, I'm afraid of that I can't find the work, and the whole year will pass like this. Sometimes I feel I am useless myself unability, because many people say that it is easy to find the job, but i don't think so. I'm stupid, I don't have confidence. If nothing is no changes what i can do about this situation the thing . Who can tell me what I should do ?????
