Housing advice needed please

34F I'm living in a static caravan with my boyfriend because I was revenge evicted 2 years ago. I suffer from mental health issues (BPD, Asperges and depression) and have no support network, no friends or family nothing I'm also on benefits and have fucked up my credit due to struggling with debt. Where I live it's noisy (my neighbour blasts rave music), cramped and it's making my mental health worse with each passing day.

I'm trying to get signed up with Kent homechoice to go on the council list but they've said it can take 16 weeks for them to just look at an application and I may not be eligible because I've not lived in the borough for 2 years.

I can't rent without a guarantor and I don't have a guarantor, what can I do? I've been looking around on Gumtree for private landlords but I'm not having a lot of luck, I can't live in a shared room or anything like that I need my own space and that. Has anyone been in this boat if so what did they do to find a place?
