Should I go to boarding school?

hello everyone, so my first year of high school is raping up. I am currently going to a jewish private school. which I do not like because well a I got no friends there but what the hell. and b because I am an atheist I am all ways being told that I will "burn in hell" (not sure how that works because jews don't have a hell described in the torah do they?) and c, I have to take four extra classes, hebrew, Bible (or torah or Thanh or whatever it called) rabbinices (jewish tradition ) and jewish history it is lowerING MY mark by 15 PERCENT. so after a year of convincing my dad he is okay with me switching to another school. however, hey would still like me to go to a private school. I also agree that most private schools have better education then public schools, even the one I go to know (it gives me Better education but at the price of lower my marks form the 70s which is almost okay in my dads eye and is okay for now in mine, to an 58! which is a failure in my eyes, also I got no friends there so not attached to my current school, also people tell me everything I am and I stand for is wrong and unholy, so if I could go to a school were I would not be told "you'll burn in hell because you parents are intermarried" I would be happy) anyways I cant get accepted to the public high school I might want to go to where my friends are, so I started looking online and there are some that are affordable in my dads budget (boarding schools because there like 100km-500km away form my home) so what do you guys think? should I go to boarding school? or is it just for people whose family is messed (just my mom is messed as in she threatens to leave the country and go to israel if I switch schools... I don't think she is serious because she has no job) how hard is it to adapt to boarding school seeing as I have a physical disability, I can walk but a like 3.5KM or half as fast the average person and only for short periods of time. thanks
