Firstly congratulations on your weight loss, you have done so well and should be very proud of yourself
I'm a LighterLifer myself so I can chuck in a few ideas that you should be able to relate to before you decide to chuck it all in for a plan with limited additional counselling to help you with your issues.
Firstly, have you spoken to your LL counsellor about your fears and difficulties? LL is set up to support those re-entering the world of food so although you have only experienced the weight loss bit of the programme I can tell you that I found the management and reintroduction bit of the programme totally amazing. It is was LL is all about
I have learnt more about myself and how to deal with my particular problems than I ever did on foundation and development I found was a wash out for me.
I'm sorry if I have got this wrong but my impression of your situation is that this is the time when you need the most help, this is the turning point of your diet.
Please try going back to your foundation book and read through it all again, especially the bits about crooked all or nothing thinking. Try to put some of your present insecurities into some sort of order by doing this. Maybe have a look at my management diary thread too and just read my posts to prove that an all or nothing thinker can be reformed and have blips and know that this isn't the end of the world and doesn't spell the end of the diet no matter how hard it is at the moment.
With LL you get suuport from a trained counsellor to help you through because the hard bit is keeping the weight off rather than losing it in the first place. My personal opion is that times of self doubt and massive challenges are when you need more support, not less
Good luck with whatever you decide and please keep us posted if you can. Whatever you decide to do you will find support for your way so I hope you can keep looking in on the forum
