What is the best place to stay? School or home

Basically I'm not that social, at school I'm literally a ghost, I'm more ignored than not, besides that they only talk to me out of interest sometimes (to do math homework).Today at school was horrible, it seems that my conclusions were only confirmed but I also remembered the bad times when I suffered heavy bullying to the point that I had depression, in short, I I'm kind of a ghost at school, I get bullied sometimes/rarely, I don't have friends I can trust, my school prohibits the use of cell phones to make things worse... but if you compare it to the situation in home. Oh the weather is horrible, my parents and my sister are always arguing, my mother She takes her anger out on me, threatens me with the worst possible things, keeps humiliating me, lowering my self-esteem and worst of all, my whole family still helps me, I don't know where to be without being the one I need someone to help me... I'm just a little kid wanting attention from my parents and friendship. This was my rant, sorry if it's too much of an opinion or drama on my part, but this was just about today, there was worse days and I apologize for the thousand mistakes in English, I'm Brazilian.XD
