Yes, it sounds like a hard day. If my car died on the side of the road I would have had to call someone to fix it so you did better than I would have done. Mornings are my worst time of day too both physically and mentally. By lunchtime I feel better. Its like you made it thru half the day. I understand, your life sounds like mine, loneliness, work and responsibilities. It sounds like the beginnings of depression. Don't let it take hold of you. Fight so it doesn't suck you in. You may want to try counseling, or look into some outside interests and or hobbies to give you an escape from a life of just work. Hope things get better. Best wishes.
