I know exactly how you feel, and to be honest not being in control of the issue was more stressful than the weight itself for me. In the end I decided to join Weight Watchers and do something about it.
I've only lost a small amount (compared to what I need to lose to be at my goal weight, which is what my ticker shows), but I already feel like the clouds have lifted a bit just because I feel in control of the situation.
Also I had my first dress fitting tonight and just seeing me in a sewn up bit of calico changed my whole outlook on the situation. I felt special and like a bride and couldn't have cared less about my weight. Hopefully you'll put your dress on and feel the same way.
Lastly, don't listen to other people. They don't live your life, or have your body. Only you know what's going on with you. If you're unhappy then you need to change the situation for you, not because someone else tells you to loose weight.

Two little things to leave you with. 1) You're H2B loves you as you are, and that's all that matters really. 2) If anyone comments on your weight come back at them with this saying (my Dad used to use this one on a particularly nasty woman he worked with): "I may be fat, but you're ugly, and I can diet!"
Chin up hun!
