Jay's Journey

I'm just looking for help, anything really. I'm a 32 year old male, who's 6'6" and probably 260lbs. I Googled weight loss and ended up here. There isn't much to my story, I got very ill early last year, found out I was diabetic, lost the toes on my right foot, part of my right lung, and most of the muscle in my right leg. Fast forward a year and here we are. I need to lose weight and get healthy. I hate the way I look and feel. I hate that I haven't regained any of the stamina or endurance I had (not that it was a lot to begin wit). I just hate where I'm at. I know things need to change. I'm writing this to try keep myself motivated, and I hope someone reads it and stays on me to keep at it. I need to change everything about my health. I don't eat a lot, but what I do eat is terrible for me. I'm kind of a picky eater, but that has to change. I installed a health app on my phone, and started to count calories. I'm using the pedometer to track my steps. I really don't have any idea what I am doing, or should do. I know there is a lot of bad information out there so I guess I want someone to point me in the right direction. I am terribly out of shape, and have very little endurance and strength. Any and all help or advice will be appreciated. Today is day one of the rest of my life.
