I'm with the sentiment of not looking back but looking forwards and becoming healthier, I can safely say my diet and lifestyle now is so much healthier than that of any one of my friends or family and a lot of chronic conditions are leaving me. I'm planning on living my best life, sure I have the diabetes demon on my back but you know what? I'm doing strength training
Don't blame yourself, you're doing your best and
@Brunneria said it all so well, it's what you choose to do now which is important and here's a good point too, those people that don't have it probably don't know they do or are brewing a worse end than you ever would do with a good and healthy lifestyle.
