Don't want to do anything.

I'm in the middle of a bout of another bout with depression and I'm at the point of just not wanting to do anything. I just can't muster the willpower. I'm at work alone in the office right now. No one was here today so I came in two hours late and not I'm just kinda sitting here. Not doing my job, but also not really doing anything else either. I'm just sitting here maybe I'll kinda browse but not really. I'm just stuck and feel like shit, but mainly numb. I kinda just want to leave and go to bed. I'd is there anything I can do to help get out of this? It's taken me a really long time just to write this.
