Hey and welcome. You're in the right place -this forum is invaluable for support and advice, as somebody already mentioned it will help you to get back on track even if you feel it's going wrong. (Others success stories and pictures are really inspirational, too.) I know you have more weight to lose than I do but we are all in the same boat whatever our targets are, and having others who are going through the same thing to talk to is great.
If you feel so strongly about what you weigh try to use those feelings to drive you, that's what I've done. If I am having a day where I feel angry or bothered about how I look, after a few minutes I tell myself "well then get up and do something about it, sitting feeling sorry for yourself wont help and nobody else can do it for you". It's a real frame of mind to get into, but I find I can channel those feelings into motivation, almost an "I'll show them" kind of feeling.
I am doing better with my weightloss than I ever have in the past because of a few things; 1. I'm thinking long term, and about changing my ways for life rather than just "oh i need a diet". 2. This forum really does keep me on track and hopeful, and 3. because I've finally accepted that the only way to get how I want to be is through hard work, there's no other way and I can avoid it or get stuck in.
It's a long hard road but it's gotta be done if we want to change, and I really do think when I get to my target weight it will all be worth it.
I look forward to reading about your progress in your diary.
