Contemplating giong back to work

About every few months I go through this - I start thinking about going back to work.  I never intended to be a stay at home mum but with all that's happened, I found I couldn't actually work.  So now I go back and forth on what to do with my life, much as I always have really!  I mean I have this dream to start my own business and I have been working on it, but there is also the draw of being out in the workforce.  I don't 'have' to work, though it would help our family do all the extras that we would like to do ... like our trip to North America later this year - a part time job now would mean extra spending money while there.  And we are also thinking about buying some property that would help us towards our 'ultimate dream'.  I already have the kids in care 4 mornings a week and I wanted to use this time to work on my business (I'll discuss this more at another time) but I always end up fluffing around on the computer.  I could be out working during this time.  This past week I've been a bit down and I think sometimes I just miss being around other people.  The kids are gone, and I'm home alone and I this past week I have found that I've really been missing my friends from back home.  It's a lot of time to be on my own.  Anyway just a short one for now as I need to go get my boys but just wanted to get it out.  I'm contemplating working again.
