Stressed and don’t know what to do!

I just got out of a toxic 5 year relationship. Granted he paid for some of my bills but materialistic things don’t buy love. So now here I am struggling to find a way how I’m going to pay for my bills. I’ve been applying left and right to jobs (because where I currently am it’s only part time and I’m not on payroll). I had to switch to my own phone plan which I’m being charged $156/ month for 1 phone. I can’t afford it!! But I also can’t go to a different company because I would have to pay the rest of my phone off which is like $600. Idk what to do?? Someone please give me tips or maybe if you’ve been in this situation before what helped you or what you did?

Im 22 years old if that matters
