Hey guys please help me out?

hi friends i'm 21yrs female. my mom irritates me. she doesn't let me go to the colleges like my cousins and my friends are studying. therefore i'm studying under distance education. she doesn't let me go anywhere or hangout with friends . all the day i stay at home feeling lonely as i don't have any siblings and my dad passed away 6 yrs ago. she gets irritated whenever my friends calls me. specially when my best friend calls me. overall she doesn't allow me to talk 2 my friends. and all the day she yells horribly on me for no reason. My mom is ruining my life. well she scold my best friend for no reason and blames me for everything. she wants me not to make friends with anyone. Little things make her mad and she yells at me even when I don't deserve it. for all those reasons i always cry sitting alone in my room. i feel like i'm locked up inside my own house. i want to be free and enjoy my life but i have no one to share my feelings. it sometimes feels like she doesnt care about my feelings at all. and thats why i feel depressed and lonely. i broke up with my boyfriend only because of my mom. my boyfrnd used to give her a lot respect but one day she got super mad and behaved rudely with him again for no reason and threatened him to break our relationship . her mind keeps on changing all the time can't take any decision properly and its spoiling my life. she is such a kind of lady that if she likes someone from her heart it won't take a minute to change her mind and the same person will become enemy for her . she talks to me too much stupidly and it;s annoying. my life is so messed up. now the situation is really unbearable. i want to leave my home but i can't coz i have nowhere to go. or i'll commit suicide.
