Hello,
I think the first thing I would do is schedule an appt with my doctor. He can tell you if there is an underlying cause to your weight problem, maybe thyroid, sleep apnea, diabetes, emotional eater, etc.
Some of these things can make it difficult to lose weight no matter what you try. Once you get treated for these issues, it might be easier to lose weight. I have all of these conditions. People know little about sleep apnea, but it can really mess up your system. The brain is deprived of oxygen at night, which makes things almost impossible to do during the day and it can also throw the metabolism out of whack. I sleep with a CPAP machine and it changed my life.
So please, don't give up, there is help out there and hope out there!
