Hi OP,
If you are still reading this, I admire your determination !
You are clearly a fighter! You know what you want! and that's powerful!
There is nothing wrong with admitting what you are not willing to try, you have your own experiences, your own reasons for that, and that's perfectly fine!
Many are missing the point that you are aware of what you don't want, but that doesn't mean you are refusing help! you are determinate to look for other options! Something that would work for you!
Reading the advice: "go to your GP" I totally appreciate the reasons behind that advice,
however my personal experience taught me, if I am not morbidly obese: "sorry, there is nothing there for you. Just Exercise more and eat healthy"
(If I get a penny for every time I head that 'advice' while looking for help!)
That was 3 years ago, I went and give anything a try! (I tried Overeaters Anonymous - well, this is just my opinion, but WOW, they really know how to mess with your head! I did give it a go, but left after few weeks I felt like part of the cult- really creapy)
Like yourself, I knew I can do it, I just need to find the way that works for me!
I knew I wasn't born with it! And if I have learnt something, I can un-learn it! It is a behaviour! I knew there is something I was struggling with and food was just something that helped me to cope!
"Do not look where you fell but where you slipped" - this sentence made a lot of sense to me.
I started learning about me, my emotions, my triggers.
Over the time I was able to catch it earlier and earlier!
I have not been dieting since. I dont label food as good or bad anymore! I don't feel guilty after eating! and the most amazing thing, I started loving what I have. Loving me!
I've got that huge appreciation for my body and truly loving the size I am! I feel beautiful! I look after myself now more, and it is not because I have to, I genuinely want to cherish my body!
I know I have lost weight since, but it happened naturally, without me stressing about it. I don't even know what weight I am atm, and tbh, I truly don't care!
It is such a beautiful state where my body is not a cause of my bad mood anymore. I actually see it as something to contributes to me feeling happy! and food isn't a problem anymore!
I feel like I am rambling on... :)
Not sure if this post helps.
The bottom line is, I praise your attitude!
Do what works for you! Do what you want, not what others say you should!
