35 Years Old with 1 Child by Emergency C Section - Body Now Ruined! From the UK.

I'm 35 years old and have always been a size 10-12. I've never had an athletes body or a six pack but overall I've always been content with my body. That was up until I gave birth to my baby last year. I'm now under my pre pregnancy weight but cannot shift this apron of skin fat left around my stomach. It's just awful and plays on my mind every single day. I have had to change the way I dress which now consists of baggy tops and dresses to hide in and cover up!
My little one is now 18 months and for 12 months of that I've been considering having a tt with muscle repair (about 3 inches). I've been on a rollacoaster journey thinking 'should I do this' 'am I being selfish' 'should I be putting myself at risk' etc but decided that my little boy deserved a happy confident mommy and I deserved to feel me again! I started my research at the beginning of the year (this site has been great) and met with my consultant in May. I agreed to loose a further 7lbs before surgery (which I did) and booked it in for 14th August 2015.
Between meeting my consultant and the op date I just kept myself really busy! I'm now 3 days post op so will post some before and after picks and write how the op went in more detail.

I'm 5ft 5 inches tall and weigh 11 stone (154 lbs or 70kg). I wear a UK size 12-14 but it has to be baggy around my stomach. Hate these photos..!!
