I feel stuck in my life. Any advice?

I'm 19, going on 20 in two weeks and right now, I feel I can't make any progress in my life. Since I've graduated high school two years ago, I haven't been in college due to financial aid complications. Also, I had my very first job last summer that only lasted a month before I was laid off. Now, I have no job, I'm not in school and I live with my parents. I feel very bad about myself and never thought it would be this way. I used to be a straight A student and then I lost my older brother to cancel almost 2 years ago and wham! Depression hit. I don't remember happiness anymore and I'm always in bed. I have abandoned my social life. My parents make me feel worse about myself as they say I'm doing nothing with my life. They make me feel like it's too late. Now, I know this has really become a problem because my own friends ask me why aren't I in school or have a job. No one accepts me anymore. Any advice, please? I don't know where to start.
