I need help so bad, i want this to be over and i don't want to be sick to my stomach anymore?

All these months and years my mom and dad have been telling me to get a job and i have been looking for jobs in my town and signing a lot of applications, but it is really hard to get a job here in the town that i live in. and since i don't have a job yet i have been working with my dad for his carpet company to get money but i only get paid 20 dollars a day when i work on my vacations because i haven't learned much, and last year i got a job in my school cafeteria and i didn't get paid enough money and my pay check went up to only 60 dollars in one month because i got cut off due to a low grade and i only got to work for a month instead of a whole year like i should and i got that job by the help of my friend titus who graduated last year, but hes not going to be in school this year anymore. so now that i don't drive or have a job my dad was telling me if i don't get a job within 30 days after school starts i'm going to be forced to drop out of high school this senior year that's going to be my last year and go live with him and my mom agrees when they talk about that but i seriously don't want that because his new wife is mean to me and it gets me to nervous and my dad not protective over me me at all like my mom my brothers and my sisters and he always lets her start drama with me and he even said he is not gonna be protective over me i'm always feeling sick to my stomach thinking of alll this and i'm always thinking about this and feeling sick to my stomach and when i look at the photos in my sisters digital camera that i took at the high school graduation with my friend that graduated this year my eyes get watery and i feel like i want to cry because of how nervous that they are getting me because of how i might not get a job and not be able to graduate with my friends my upcoming senior year. i sometimes cry at night and i'm always shivering and feeling sick to my stomach and i just want to get a job fast so i can stay in the town i live in and help my mom with the rent that we need to pay and end all this, can i please get some help and answers, i really need it please help me ="(
