2 years after I had my son

It's been now two years since I had my son and body is in bad shape . I've never lost the weight I gained during pregnancy and now am so Fat! I weigh 265!!! My arms are fat my middle is fat and my thighs. My body no longer feels the same. The worse part is I have an umbilical herina that split so I can't really work out because I have no core. 
My body really took a beating during childbirth , I was in labor 26 hours and then had to have an emergency C section my body got so swollen and my legs were huge.  I can't blame it all on baby birth and c section, it also has to do with not really working out and then eating late nights because of work. Now I want to lose some wieght and feel good about myself . Just feel all my friends who had kids bounced back and me I still look preggo. My husband says I'm beautiful but he is a good man. Sorry is a long story but how many moms are still struggling with the wieght and feeling just stuck? I love my son very much he is the best thing about our life but I feel my body is in chaos.... what can I do?
