Jolly music= jolly MOOD???

If only my mood was a jolly as the music I'm listening to. I confess, my 2 day back and already,  it feels like I never been off. I'm stressing, drinking coffee, eating less, my back hurts more then ever, im slowly becoming this horrible detail noticing person. I been starring at skins on screens these 2 days, now I got bad skin radar on mode and I don't move. You could say I'm glued to the chair.
I'm on the bus, seeing other mums with their child in the push chair.
I can't help not be sad or feel tears burning. I left work early 4.45 was my set time but as always something to do so 5.03. 9-5 should be normal working hours right? Not in my world.
It's strange, back home in the children friendly capital Stockholm, you spot parents more. 
But here- NOOO.. A lot of people I work with are older then me.  And does not have child/children, rents a room in a shared home often single and suffers from workaholic syndrome along with nicotine addiction and have no time for exersice but knows how to drink away evenings...
I remember being back in Stockholm on the tube you took for granted that they  were going home to their family to have dinner And put their children to bed.
But here in London it's just not the same thing. I honestly never come across anyway saying I need to go home and example: drive my kid to swimming lessons, cook dinner, read a bedtime story etc etc. Not once! But I hear a lot I'm working over time, im gonna be late, I need to bring work home with me.... Work work work.

No wonder, why I'm not so jolly.
