THE FEELING OF LONLINESS

I don't know what do do anymore. I am angry all the time and have been for since I can remember. I don't know why I'm so angry and I sure don't know what to do. No one listens to me, especially my mom. My family has enough problems with my sister being an adult and still living off our dads money. She is like a child playing dress up in an adults attire. But I'm only a teenager who is moody and rude and no fun when I express my thoughts and talk about my opinions. My mom and I don't have a good mother-daughter relationship. 95% of the time I am with her I want to scream at the top of my lungs that I hate who she is. She is a gigantic gossip who talks about everyone including her daughters and (almost) ex husband. She is the most selfish woman I have ever met. Every time I see my friends with their mothers I envy the bonds and closeness. I have tried to talk to her about it several times but she just never learned how to listen. As for my father, he suggests I go to therapy or talk to him about my problems. That's just not who I am, okay? My sister went through depression when she was my age and did all sorts of drugs. The main problem with my parents is that one of them thinks I am going to become my sister and the other thinks I am this angel baby who she never has to worry about. Last night I slammed my fridge so hard, I broke it. Lately, all I have wanted to do was cry, cry, cry. And i hate myself for it. I feel so alone. And the worst part is that my best friend (who is also my cousin) doesn't understand that when people feel certain kinds of way, they need to talk to someone. She tells me "They'll get over it." But the truth is that they won't and that it's not FUNFUNFUN all the damn time. Can someone please help me stop being so angry.
