Extreme depression..

So much has been going on lately and I've been overwhelmed with all the stress. I thought that things were getting a little better but it's only getting worse. I wish my Mom could be more supportive of me pursuing my education on something I at least like to do but I guess not. Recently she got in an argument with my sisters and decided not to sleep at my sister's house anymore. Our house isn't done remodeling, so she's been staying with my sister. She's mad about everything and everyone. She's sleeping down at the batting range now since my sisters didn't like the idea of her sleeping at my uncle's (not really related to him). I've been trying to focus in school and getting back on my feet but it's so hard when a billion of things are going on in my life. I've been drinking a lot lately and although I know it's bad I feel like it's the only thing that makes me happy for just a bit. That's all I really need to feel a slight bit better. I'm having issues with some friends. Especially M. He's supposed to be my closest friend, someone I can talk to without having to feel offended or judged but he's changed. He's a total different person now and I'm so fed up with his shit, I couldn't care less. He told me that he thinks I'm just making up excuses not to be happy about my life and drinking it away. If I could be happy, I swear I'd do anything to just be happy. It's so much easier said than done. Everybody goes through things differently and that was just offensive what he said. I thought out of everyone he would be the only one to understand but I guess I was wrong. I don't need any of this nor do I want any of it. I'm also going through stuff with B and J. I'm sick of helping people who are just gonna act and do what they want. Now that they are making it worse I'm done hanging. J told B that I've been calling him and talking to him and sometimes at 3 AM. I accidentally called him late one time when I was trying to call M. Also I don't call him everyday. When we talk it's most likely always about them and how they are trying to get over each other. It's annoying and time consuming. I didn't sign up for this, I was jus trying to be there for them. So B thinks I like J but has no guts to come ask me herself, so she's throwing tantrums at everyone else. I see why I did't want to hang out with a group in the first place. There's always drama no matter what I do. I don't want to hang out anymore. I confronted J and told him I'm done with their bs. I have family problems at home and so many other shit, I don't need their add ons. I miss my dad so much. My sisters and I had a very long talk today about my parents. I just realized how fucked up my childhood was. I was always the one at home to see every messed up aspect of life in my family. My parents used to argue and literally fight and even try to kill one another. I witness all the drama, all the pain, and just everything period. People always tell me I strike them as a very depressed person. Well, how am I supposed to be happy when nothing's happy to me. I need time alone. I need to stop drinking, which I will soon. I need to get out of here and do me for a bit. I'm thinking about studying abroad. I don't want to be here anymore. Everything is depressing. The people, the memories, and the present. I wish life had a control where you can fast forward to the happy ending part of life..
