Well, although this might not be quick, but it would help achieve a goal in the long run.
What you are saying is a common problem. I was diagnosed for anxiety and depression early last year.
Before this I had begun weight loss program with the aim of bringing control to myself.
The weight loss program helped me get my control back on track and I could easily handle Cognitive behavioral therapy (CBT) for the anxiety and depression, however weight loss programs differs from one person to another.
In fact, some people will need the CBT work before going for weight loss plan.
What is clear from this is that mental health and mindset are the most important factors for effective weight loss.
