Welcome Jen
Tip #1: Never get discouraged and never give up on yourself.
There is a lot of information out there regarding weight loss. All of it is right....all of it is wrong. What works for one person does not work for another and vice versa. The most important thing about weight loss is realizing your goal is not in fact weight loss, but FAT loss. There is a difference.
Don't make any medical issue as a reason for why things are the way they are. That's an excuse. August 2012 I was told to file disability and that my quality of life would be limited to the reach of how far my O2 tack teether allowed me to venture. Today, I run. Change what you can, accept what you can't, and challenge what you know.
Looking forward to hearing your successes. It's a battle, but it is a battle worth fighting
