Whats wrong with me? Please help. I'm about ready to give up life. Depression? Just sad? Easy points!?

Is there an adult you can talk to? You need some help. I was like you as far as a bad home life only mine was worse then what you describe. I was happy around others and no one knew I was in bad shape. I just hung on til I got out of my home. You need to get help now because I do not think you can hang on for much longer.
