Big Girls Don't Cry...or do they??

This is my first blog in a very long time...I have been contemplating what to write for some time.  So I chose a subject that has been plaguing me for as long as I can remember.  My weight.  Yes I said it, my weight.  Now I am not going to disclose an actual number here because I'm just not that brazen.  But my weight is something I struggle with every day.  I remember being teased and tormented growing up because I was more "curvy" (and I am putting that in the nicest possible terms) than most of the other girls.  As I grew up and grew into my looks, my weight became less of an issue.  That is until I lost it...in 2007 I lost an unbelievable 60 lbs.  I couldn't remember a time when I had looked or felt that way.  For the first time, people were seeing more than just a "pretty face"....if you have every been a plus size girl you know what I'm talking about.  When you are "curvy" people always say "you have such a pretty face..."  Ugh!  Anyway, I'm getting off track.  Much to my disappointment, and as I have felt, the disappointment of those closest to me, I ended up putting most of that weight back on.  I have done the Weight Watchers thing and the Zone thing and they  provided temporary results.  I know the one thing that made all the difference in the world...say it with me EXERCISE!!  Something as a nurse, I know is beneficial, and Lord knows I should make time for but my question is how???  I work 40+ hours a week and crazy me has just accepted yet another job, and am virtually a single mother...I do have an awesome support system, but my daughter wants me when I'm not at work, no one else.  It's not personal but it seems I am the only parent taking an interest in the goings on in my 7 year old's world.  And truth be told I feel incredibly guilty at the thought of taking any "me time" when I know my daughter is waiting for me.  So what to do?  I have thought about investing in a treadmill so I can work out at home but with the single mom title comes those single mom responsibilities.  My daughter does and always will come first.  I have a gym membership that I NEVER use...that's right, the fee is automatically deducted from my checking account every month and I couldn't tell you the last time I set foot in there.  It would be different if they offered some kind of child care services but sadly they do not.  Now the Y does offer child care, but the rates are thru the roof and the equipment looks like something straight out of an 80s workout video.  So what am I to do?  I am ready to make a change...I am ready to be more than a "pretty face".  I am ready to stop feeling a certain way every time I look in the mirror...
