your 15 and still in fulltime education if you get thrown out youll get emergency council housing with a careworker and rent covered. happend to a family friend a year or 2 ago. my advice to you is stop selling things so quick. you post more stuff for sale than asda sells and then you regret it and try getting back something similar. dont get rid of it in the first place or at least give yourself a few months to actually gel and bond with the instrument before you decide "im fucked, i really need an acoustic for my band"
