What the hell???

I just keep on falling down and I don't know what to do to fix it. Work just keeps getting worse and it makes me concerned. Every Sunday and more recently every week night I just get super anxious and depressed that I have to go to work in the morning. I shouldn't feel like that I am only 23 years old after all and I shouldn't dread going to work or cry my fucking eyes out when I get home from work or when I go to bed because of it. It takes all the strength I have to even get out of bed in the morning. I haven't eaten anything but a half a piece of toast and a couple cookies since Sunday night....and even now as I write this I still am not hungry. It is becoming one screw up after another at work and I don't know what to do to fix it because every time I try to stand back up I just fall down the slippery slope again and something else makes me super subconscious. Work is the one thing that I am confident about. I know that I am a good worker, sure sometimes I miss little details but I get my work done on time and I don't stop working until it is finished. My boss even told me the other day, "you  work too hard to be feeling this low". Now that I took this job I feel like my work ethic that I have been so proud of is something that can be laughed at. I mean honestly I feel like I have lost my mind like my whole world has been turned upside down. If I am not good at doing work than what? I mean you spend over half of your life working and if it's something I am not good at what am I going to do?

Maybe it's that I don't really know what I want to do anymore. Maybe my interests have changed. I mean I know where I want to be (maybe) but I don't know how to get there. I want to help people that's why I went to school for HR but I ever since I graduated I feel like I haven't gotten anywhere close to that. What if I get stuck at this crappy job being the office bitch for the next 40 some years? What if I missed my chance of getting to where I want to because I got impatient at the credit union? What if this is all there is and you are supposed to feel like this about work? I mean are you supposed to feel like this????  Are you supposed to feel like your insides are trying to crawl their way out and you just want to puke to make yourself feel better? Are you supposed to feel so anxious on your way to work that you contemplate turning around and going home at every freeway exit? I don't think it'supposed to be that way but how do I change it without taking a big financial risk? Does anyone ever really figure it out?
