Hello and
A lot of us have started from a similar place. I'm an emotional eater too and even now after losing 26kgs, I still have to remind myself to stop indulging. It takes a lot of practice and mostly perseverance to move forward from your slip-ups and keep going. We all make mistakes at some point. At the moment, I'm letting my stress get to me and I'm indulging--often.
In the beginning, what really helped me to keep moving forward was realising that what you are doing is changing your
lifestyle. You're not
'on a diet', you're making lifelong changes. I'm not one for therapy and doctors because I know that deep inside I have the ability to see things through. We all have this ability, it's only a case of whether you believe it.
I think being 'obsessive' about weight loss is not a healthy way to think about it. Try thinking of it in terms of 'determination' and 'perseverance' to reach your goal and not be dissuaded when challenges arise. (Like the one I'm facing at the moment--a challenge that I'm going to face head on once I get my mental state in check. I'm almost there!)
And yes, do come here if you feel you are about to eat something you shouldn't. There are a number of awesome threads that can help. Try browsing the
Chicks in Control forum or the
Support Groups one.

on your journey and remember to not give up whenever challenges arise. Winning challenges (whether perfectly or imperfectly) are how we grow and move onto the next one.
