Hey! newly single and looking to lose a lot of weight

Hey! I am looking forward to hearing how single people cope with cooking and exercise. I have been on my own for 2 years after 26 years of marriage. The divorce was final in January. Now, I am looking to lose 100lbs. I am a type 2 diabetic. This is my last attempt before undergoing the surgery. Like may people I have tried everything else with no long term success. I live in the southeastern US and have a pretty decent social life. I just want my health and energy to be better so I can have some adventures!
