enjoying freelancing?

I have been freelancing for about 4 months now - for my ex-bosses and friends - but it seems like I have been doing this for years. I'm not complaining, it's just that I'm overwhelmed by the time they demand from me. I end up getting annoyed and irritated by the way I steal time, thinking I needed to finish or amend something. Choosing not to have a day job was never a hard thing for me because I always wanted to be a stay-at-home-full-time-mother-slash-wife. But now that projects came pouring in, sadly, I don't thing i have become "full-time" for my babies :( Or at least that's what I feel. 

Yes, I love the freedom it brings... the control I have over time - but why am I ranting over these things? Crap. Maybe I'm just a little uninspired with that gloomy grey sky outside my window.
