Feeling depressed

I am 25 years old. I work two jobs one is about 30 hrs a week making minimum wage (8.20) the other is a temp position working 16 hrs a week. I am also a college student classes 2 days a week. All of my family is about 6 hours from me. I love in a diff state living with my bf. I just feel that I'm at my breaking point. I don't have any days off or time to myself. I've been searching for a job and I still can't find one. I'm loosing hope. I've been here for over a year and have yet to get on my feet. I don't get why no one is hiring me. Yes o have the two job but I'm not maintaining. I won't be able to get benefits from my job. For another 15 months. I had a paper due yesterday and two classes today and haven't done either of them. 

I literally just want to lay here and cry. 

I feel like k have nothing left. My BF helps me financially and keeps telling me to stick it out things will work out but it doesn't seem like it
