Depression

I don't know if talking about depression a thing here. But I suffer from depression for almost four years now. Im 19 and everything has just been bad for me. I consider myself to be one of the most "unluckiest" person I know and I think is because I deserve it. I always know that everything that's happening is my fault. Being alone every night and have no friends or even family is really hard. I'm just tired to be depressed. I also get a lot of anxiety . And it has effect me in many ways in my daily life. Is anyone out there feeling like this too?? I hope not.
