When you feel like life is spiraling out of control?!

I have been upset lately, because I feel like I have been under appreciated. I try to do everything I can for my grandma, and I feel like she's mostly worried about her daughters. Like whatever worries me or concerns me doesn't matter. I've tried to talk to my mom and other people. But I don't feel like anyone is listening. I feel like I've just been talking at them, not to them. I feel like life is quickly spiraling out of control. I had a direction, an inspiration in life, but I'm quickly losing sight of it. I don't know what to do. I feel so alone in this world. I try to keep busy from thinking about these things but anymore I just keep getting angry with everybody. I want to stop being angry and feeling alone. What can I do?
