I feel alone what should i do please help?

at school im alone, at breaktimes and lunchtimes i go to my next lesson and wait alone, on the bus i sit alone, i have hardly any friends and the ones that are leave me for other people, i listen to music because that is when i feel ok with myself, i have noone to talk to, noone to love, nothing in my life is going good, just thought i would say this because i am feeling very down and was hoping for some suggestions on what to do
