What exactly can you do if you don't get a guarantor?

I don't even really know how I got my current apartment, but I'm looking to downsize my apartment from somewhere thats 2500/mo to.. less than that, lol

The problem I'm kind of facing is that I have bad credit after studying abroad and having a medical emergency. I have a future fulltime job assured upon graduation, but for now it's just a part time, and I graduate in May. My parents and nuclear family aren't US citizens even though I am, so they don't qualify to be my guarantors. I know I can afford my desired range and I know my parents can cover for me in the same way a guarantor can otherwise. I also know I can pay my deposit and first month upfront guaranteed.

What exactly am I looking at here for this type of situation? Like, what should I do/expect?

It feels like I'm just gonna see myself getting rejected over and over because I can't get a guarantor to cover for some of my current shorrterm shortfalls, or I'll be forced into an apartment far below what I know I can afford just to qualify. Does my plight make sense because it's been an absolute headache for me to deal with 🥲
