Overwhelmed and Depressed, Finally Breaking Down

Title pretty much says it all. It feels like life is sending me one curve ball after another and just keeps beating me down. And I have honestly had enough. I am yelling at coworkers, managers, family and friends. I am not sleeping because I keep waking up thinking about what has been happening, and recently I haven't been eating because what's the point.... I am getting scared. I have never felt like this in my life. The things that bring me joy I just don't do, and I basically work and go home and watch tv. I force myself to go to the gym but even that feels unproductive...idk if I'm even looking for an answer, I just need to vent I guess...
