Working Mother's dillemma

I know a lot of people have gone through this before me and a lot will after me and am not the only one. But posting this just to mark that I am going through this, and may be someday my daughter will also read this.
I am very bad at making a decision and sticking to it, even if its smallest of things like selecting some snack from given menu. I would struggle to arrive at something and most of the times end up regretting why I chose this and not something else. And this time the menu card showed just two things and am still struggling. One, take a break from work, watch my baby grow and give her the best of nourishment, and my entire time and attention. Two, join back work, trust others in bringing up my baby, and give her the maximum available time left after work.
Choosing One also means I will be sitting idle for some time doing nothing( even if there are hazaar things to do, my laziness takes over me) and take care of the baby rest of the time. And Choosing Two also means a super busy life, struggling and juggling and living in constant guilt that am not able to give enough time to my baby.
I knew the above before I even got preg and taking a decision seemed so very easy! Obviously the first! Welcome break from work, no pressure of getting up early and catching the bus, no work pressure, no appraisals tension. Just some happy time at home with the baby. I made the decision of taking a break from work by choice and not by force. And am also blessed enough to be able to ignore the financial aspect while taking the decision (Thank you H) .
But now, when am actually going through it, am finding it tough to be sitting at home. I never actually realised when going for work had become an addiction for me. I know I will regret the moment I will join back work, coz by then Baby would be my bigger addiction.
Inspite of knowing everything, pros,cons it sometimes just gets to me. With not so friendly neighbours, no one to show off your new dresses to and no one to talk to the entire day(am Not talking about the one sided baby talk) , and even if I meet some other mothers at the park in the evening , it's only about babies, and it just gets too much to handle. What did I used to talk about before I had a baby??
With extremely supportive H and an absolutely adorable daughter, am just sailing through this. May God bless me with more mental strength to stick to my most sensible decision I made.
