Are you happy with your body after having kids?

I have a 5 year old daughter and had her when I was 19... I was a size 12 when I fell pregnant with her, now a size 8 but by body feels awful. My are saggy from feeding any my stomach has stretch marks and has like a droopy rubbery feel to it and I have stretch marks on my thighs abd wobbly bits at the top of my legs too. I just hate it as I eat a great diet and exercise everyday and no matter what that skin will never be as firm as it once was... I want to feel y again. I am no longer with my daughters father, my ex hubby - I have been in a fresh relationship for the past few months and I feel a little self concious about my body as he is hot and I feel a little inadequate he always compliments me but however, I still feel like a rolley dog. How do I get over this..obviously if I had the money Id get a job and a tummy tuck.I wish!
