Job advice

Hey guys, i couldn’t find any help elsewhere so i thought maybe you could help me out cause I’m really at a breaking point, so I work at the airport, as a subcontracting agent for the national office of airports a job that i didn’t want at first but my uncle who happens to be an army general and my parents convinced me to accept it and they promised that I’m gonna be promoted to another place and still i can’t see nthg, the funny thing is that i succeeded at getting a job with La ROYAL AIR MAROC with a very interesting salary and many other incentives but they said no. I graduated with honors last year from a school specialsed in this field and also in the flight attendant’s, I have many job experiences and three English language certificates with A C1 grade, basically my curriculum vitae is good, my work schedule consists for me to work from 6 am to 6pm a 12 hours shift, and the next day a night shift which also starts from 6pm to 6am, and then I have a 48 hours off, what I have been struggling with first of all is the salary that ends by the 10th of the each month, which is supposed to keep me going till the end of the month, another thing is that this toxicity my co-workers started to throw on me, like leave our office and leave me stuck for 2 hours to 5 hours when I need to eat or have my break, or maybe even sometimes blame me for something I didn’t do, what I wanted to say is that I know I can get a better job, but my family keeps insisting on me continuing doing my job and maybe some day it’ll get better, what they don’t understand is that the hell and shit I get to deal with on a daily basis, my sleep schedule is shit, my team is shit, salary is shit.

I NEED HELP ASAP.
