When you really can't help but be down on yourself?

I'm trying hard to be okay. I picked up yoga. I go to school. I work full-time. I ride my bike. I have been eating healthy. I've even been dating a little, but I'm still so damn sad.

Today at work (and basically all night last night) I was either crying or on the verge of tears. I've felt like this for two months now. I had a crappy "break up" and I'm starting to realize that I'm 24 and still live at home, don't have the means to move out on my own, have a very unstable job (still looking for career-worthy stuff), and I am, as of yesterday, the only person left who isn't engaged. I'm also the only one who lives at home.

I feel like I failed at life or something. I have a job where I make decent money, but if I don't meet sales goals I am fired in an instant so I can't risk moving out with rent by me being near $1200 for a studio and being unemployed. I ended a relationship for the millionth time because I was incredibly disrespected. I don't understand why I can't be treated right when I treat people nicely. I went to college. I thought I could find a halfway decent job with my degree, but not a thing in two years. I've been dating but it's almost embarrassing when I talk about what I do for a living because it's an undesirable position and I am not really proud of it. Ugh.

Hopefully good times are coming still.
