Overwhelmed

Well, here goes my day so far...its midnight right now, so its pretty much over, but just thought id share a little bit of it..I started off, waking up, on time, and not being completely tired, or exhausted. Good start, right? Its cold out, so of course I forget my jacket, by the way, I got into an arguement before I leave the house, so of course Im in a bad, I dont give a crap mood. I get stuck behind a slow truck, which really made me mad. I get to work, I have three people coming at me with questions, before i have any idea whats going on yet. I back them off a little bit, and realize ive only been awake for an hour, and im already overwhelmed. I take a step back, re-evaluate. I get better. I drink my coffee. I relax. I make it through. I make up with the person i was argueing with that morning. I always fall back into that. I am a sucker for that. WTF. anyways, work goes by quick, i get done pretty much everything i set out to get done,and everything works out. its actually still light out when im done. I get home, i get to see my beautiful kids. All in all sounds like a good day considering what couldve happened had it not gotten better, right? Then why do I feel like im getting ready to go to bed unsatisfied by how my day went and ended?
