I would like to start loosing weight.

I would love to loose this extra person I carry around with me everyday.  I need to loose about 52lbs and it is so hard.  I think I'm going to try to count my calories and watch my sugar intake.  I love chocolate way to much.  But I need to make some changes now especially since I reach the big 40.  I'm tired of feeling ugly and fat.  I need a change.  My hubby is great no matter what I do.  I love him so much. I'm so thankful for him.  I wouldn't change him for the world.  I just feel so ugly and I don't know I think I am going threw the mid life crises.  I just started feeling so horrible lately But I'm the only one who can change the way I feel about myself and make a difference.  I think I'm going to start a exercise class.  I would love to learn the zumba dance I think that would be so much fun to learn how to do.  I love dancing.  Any ideas would be appreciated.  Thank you
