Idk man. Homelessness will kinda suck anyway, because you have no place to rest, usually struggle to get enough food etc. Bad weather will make things much worse. Solitary is considered to be one of the worst kinds of prison sentences, unless you're like a target for others for some reason. And high school can go either way. Mine was great, but it can definitely suck for some. But without others, how exactly is it a school? Maybe in some extreme cases of bullying, it might be better, but I think for most the loneliness will be far worse.
