feeling empty and guilty 2 day

Well its almost monday now, i worked all day, came home, did a bunch of stuff here, and i feel kinda ok today, very isolated day, except for a few conversations here and there at work, but 8.5 hours of mostly dead time, doesn't feel good to me. I am tired, not physically but mentally tonight, both my son and I cant sleep, so we are laying heretalking. I think he is lonely all day when i'm gone to work, and he is getting depressed, not real bad, but i see him feeling it. Plus i asked him and he said yeah kinda. He has been bummed when i tell him i have to work lately. I feel like its not good leaving him alone all day, i dont like it, but really have no choice. I want some kind of change in my situation. I'm thinking of what to do about it. I feel blah, when i think about this. I feel blah kind of down about life in general, thats my mood today.
