All of what everyone describes is perfectly NORMAL, so really, don't beat yourself up over it. I think some reading might be just the trick. Dr. Phil's Weight Loss solution really deals with a lot of the psychological issues that made us heavy to begin with, and even when you lose the weight, you still have the issues, you also may feel much more vulnerable in your smaller self, all very normal
, I think taking a new class, maybe yoga, is very relaxing, is great for the psyche and will help you sleep better, even a regular massage could be great!
Francis Kuffel wrote a great book "Passing For Thin" which I think would be a great self-help read, you can get it at your local library or bookstore, it's an awesome and inspiring book.
I don't think you need to be on anti-depressents, I think you just need time & reflection to get used to the new you and like I said, exercise is a great way to be more in control of your body, and in return, more in control of how you feel about your body.
I pray for you to have strength, wisdom and courage for all you've accomplished, you're doing great!
