Sweetie you are so not whingeing! It's great to be able to hear how you're doing and see if we can help - this losing weight thing is not easy, we all know that! And in any case this is your diary and you can say whatever you like on it!
I think going back to SW class is a fab idea - everyone is in the same boat and having the same struggles, and is there to support each other - so do it, find a class now, contact the consultant and you will feel much happier. If the consultant is a good one they will help you get through the door. If not, find one who will.
I'm guessing there are other things going on that are making you feel so anxious and turning to food/wine for comfort? God knows, I have been there many times - but it did help me to try and break the problems down and see what I could do about sorting out each thing. Sometimes it's not possible to do that, I know, but dealing with them as separate issues was much more doable than seeing them as one big problem that can quite frankly be terrifying and overwhelming.
Big big hugs, El, we're all here for you, love xxxx
