How long did it take you to transition to the working life again?

I feel really terrible because I am only working part time (24-30 hours/week) and still SAH Friday through Monday and I am just not feeling the work thing.

I never expected this. I am a dedicated hard worker but I feel like I'm going to have a nervous breakdown. Does it get easier? DS is 9 months old and I have been working for 5 weeks now.

Several of my real life friends have told me how hard it is to go back to work but they all seem like they're holding their sanity together well.
