Advice on making extra money???

G

So my job is giving me 4 hours a week and it’s been this way for 3 weeks now and I have one day next week as well. I talked to the manager and they won’t give me more hours bc sales are down but my co workers are getting way more hours than me and I feel like I’m getting the bare fucking minimum.

I’m getting paid $45 a week and I’ve started listing things on Facebook to sell to try to make extra cash but I mainly just have books and I don’t think many people want to buy books.

I have a deadline of June 1st to have a $550 deposit and first months rent which is $500 and I can’t even save anything because I can barley buy gas.

I’ve talked and talked to management but they say they can’t give me more hours and I’m starting to panic. I’m failing my current classes because I’m so stressed, I’m trying to find a new job or a second one but it’s extremely difficult, I’ve applied literally everywhere.

I have no idea what to do and need help urgently
