Lost and sad

Hi here I am again coming to this site again now is a situation I myself feeling so sad and lost in a way where I don't even what to do with my life recently a lot of people keep judging me a lot and keep giving me rude nickname called me idiot and stupid or maybe crazy as well.... I don't understand just a small thing and you can make it until so big then you keep on and keep on repeating and repeating is like making fun of me.... Like I don't have any feelings.. Yeah what I do maybe you think is crazy and idiot person may do but I think is worth it.... Can anyone tell me what should I really do ????
