I am not giving up..

Thank goodness I got that part-time job yesterday. Part-time is better than no-time. I received an email today informing me I was not hired for a job I had completely had my hopes up for. This is about the 6th job I have not been hired for in the last 4 months. What is wrong? What am I not doing? I am a certified nurse aide with two years experience. Along with plenty of work experience in customer service. It sure makes me feel worthless when the only employer who will hire me is a clothing store. At least my boyfriend will be with me. But that doesn't make up for not working where I truly wanted to. I am still going to keep looking for a decent job. Wish me luck :)
