My sister is in a similar position. She's sitting at home with a Bachelor's Degree in Human Resources, and the only job she was able to secure in the last year was Cashier at 7-11.
It's a tough market out there, and I know it's probably not what you want to hear, but you just gotta keep trying. If I can get a job, anybody can. It may take time but if you are persistent and cast your net out wide enough, somebody will be willing to give you a chance.
It's only over if you stop applying. Don't give up. I went through probably forty rejection letters before Salvation Army extended me the offer. You just gotta push through the rejection and keep fighting.
