Hello, Alogan23, and welcome to Psych Central! I can understand why you would feel frustrated, disappointed, and then depressed.
I have a thought: You say you're only working part-time. I know you're likely tired, but how about advertising around and taking one of those freelance odd jobs? That will give you some experience, and then when you interview you can have a resume that says: "Worked for the following companies/agencies as a free-lancer," maybe explaining the specifics of what you did. Plus you will have some people to ask for letters of recommendation.
I think that's worth a thought. I honestly think you are giving up too easily. From what I have observed, not that many grads these days go right into their dream jobs.
Okay?
