I feel like my life is in shambles?

I am 25 and everyday I feel like a new crappy thing has happened. I graduated with a Bachelor's degree and then moved to go to school and get my Master's degree. I completed all my coursework and internships, but I felt so overwhelmed and had extreme anxiety about my thesis so I never finished it. I've been avoiding going back to it and feel like I wasted a lot of money, time, and effort on grad school to not even have my degree. I've been unemployed since I graduated and no place will hire me because places that I am qualified for I don't have the Master's degree so they will not hire me and places like Walmart and McDonalds won't hire me either. I've applied to seriously like 200 jobs and I've only had 4 interviews. I took a job class to figure out to make myself more marketable, but I just feel defeated and stuck. My boyfriend lives with me and he pays the rent for us while we are supposed to split the bills. I never have money to split the bills though, so every month is a struggle. My dad passed away 7yrs ago and my mom is not in a financial place to help me either. My car that I bought when I was a teenager recently broke down and was going to cost $2k to fix, so I sold it as is to a guy for $300. Now I have no car, no job, I have creditors calling me all the time and I just feel so awful all the time. I know in terms of other peoples' lives, mine is far from bad, but I seriously cannot stand being in this position anymore and I can't figure out how to get out. It's like a bad circle because I don't have the energy to deal with my life and so it keeps getting worse. I am so thankful for my family and my boyfriend because without them I would definitely be homeless. How can I make myself feel better and get out of this??
