Thinking of you too Em...
It really isn't easy when people we love and care about say things like your dad did. I am sure when the weight starts dropping off (as it will), he will see how your inner confidence grows, you become healthier and his attitude will change.
Heck, if not you still have us - this forum has really helped me through some tricky (understatement!) times.
I think those of us that have more demons to battle get more out of the group meetings, and consequently find that in the long term we learn more about ourselves and how to cope. It may seem a bit of a monster at the moment... so many things that need addressing, don't know where to start etc... but it does get easier. Just something as (relatively) minor as getting confidence in yourself physically, goes a ridiculously long way to helping you emotionally and so forth.
We are all rooting for you on here Em - you seem like a really switched on girl, and I have no doubt in my mind that you will be one of the success stories on this site, and in life in general.
I, too, have long been an 'almost' girl. Loads of good intentions, able to preach with the best of them, but not the best at crossing the finish line or gulping down my own medicine. I think this is the reason why I ended up ALMOST (damn, I hate that word - but not in this context) sabotaging my efforts by lapsing through December. I took everyone's positive comments to heart and started to believe them when they told me I should be ready to start eating again... once again investing too much energy into listening to other people rather than myself. BIG BIG mistake.
Anyway - you know deep down that you want to make some changes - and Lighter Life really can do so much for you - not just give you the power to lose weight VERY fast, but also to help you take stock of your feelings and emotions.
Before I started I had major anxiety/panic issues... barely leaving the house and NEVER doing anything outside of my 'safety net'... but once on Foundation I felt huge self-worth and didn't have a problem for months... only having a slight return to my previous ways once the lapses started... there is a lot to be said for taking control of your life, and 'owning' yourself.
I hope this doesn't sound to cliched and too buzz-wordy... it is genuinely an amazing programme that can help you infinitely if you let it.
You can do this Em... honestly... try not to let the negative thoughts take over - it is good to get a rounded view of what to expect, but my advice between now and when you start is to keep your head down and try and only think about the future.... picture yourself how you want to be... become a self-fulfilling prophecy of the RIGHT kind.

(PS... Sorry I didn't come back and post a few days ago as promised, I had a read through of everyone elses replies and they seemed to have nailed it! I'm here if you need me..)
