You are definitely not alone. I have a college degree and I have been out of school for close to three years. I have had 5 different job and none has lasted more than six month. Each has paid minimum wage or just barely above it and I have an enormous amount of student loan debt that I cannot afford to pay back. My education has not been an asset in my job search or contributed to receiving a higher pay, as I was told it would from a very young age. I have no doubt that I am an intelligent and capable being, yet somehow unemployable.

Maybe try looking for jobs in a similar field but without the education requirement. If you are interested in psychology, look into mental health jobs that don't require as much education as a psychologist. Try to get on somewhere as support staff. It might not pay well but it would get you experience in the field.
