Hi, everyone!
I see a few familiar faces (or avatars) and quite a lot of new ones in all the recent posts, so I figure I'd best reintroduce myself, since I've been away for about a year.
I'm Telorida, I'm 30 years old, recently married, and desperately trying to lose weight. I've been in the 300 lb club for several years, and have been trying off-and-on with varied success to try to lose weight. Last time I was here, I faded away from the forum last April because I moved on to a forum that was just based on Atkins (the diet I shifted to), and I hung on to my dieting ways kind of loosely until about August, until the stress of buying a house, moving, planning a wedding, and changing jobs all got me overwhelmed. Of course, once I fell off, I did not manage to get things together until well after the holidays.
This February, my husband and I restarted low-carb together, but we put in a half-a$$ed effort, cheating regularly on the weekends when we were in social eating situations. So I went from 319-310 but kind of stuck there until April. Now, I’m back again, with the intent of redoubling my efforts and getting really serious about dropping the weight.
So what makes this time different? Well, in April my husband and I went on our belated honeymoon. We went to a lovely place in Jamaica, right on the rocky cliffs of the seaside. You could jump in to the water from low (or high) cliffs and then climb back out via a ladder. It was great!
Until I went to climb back out.
I did not have the upper-body and core strength to hoist myself up the ladder rungs. To be fair, I later heard someone fit complaining that the ladder was difficult. But my shape made the climb more difficult than it otherwise might have been, as well. (I mean that my stomach pushed me farther out from the ladder than another person, so I could not put my center of gravity over my legs.) In the end, my husband and another man had to each take one of my hands and PULL while my feet scrambled for the next rung up, then let me rest before doing it again. I was mortified… just completely mortified.
Every time I read the story of someone’s weight loss success that has been consistent and maintained, they had a rock-bottom story… some kind of wake-up experience. Well, that was mine. Until now, I’ve been able to fool myself into thinking that, yeah, I wanted to lose weight, but I could still get out and do things if I wanted to. Being faced with the truth really hurt.
But it’s all uphill from here, right?

) , is that it can only get better from then on! I can't imagine how that moment must have felt and I'm so sorry that it had to happen to you. But what a great situation to use as fuel for motivation and to stay on track!
It's hard to have something like that happen, but you can use it to change your life! You will do it! 
but I know I must so I can jump off the cliff like you.
