Hey everyone,
I'm a first-time poster on The Knot but have been lurking since I got engaged last fall. (I really enjoy all the truth-telling that happens on the Etiquette board, even if some of the question-askers don't appreciate it so much ...

) Anyway, I guess what's prompted this is that in terms of getting in shape, I'm kind of feeling like I'm at the end of my rope, so I thought maybe someone could offer some comfort or maybe even suggestions of what to do at this point. I'm getting married on Sept. 21, and have been trying and failing to lose ~10lbs since about January, having started at roughly 136 lbs (I'm 5'4''). I had some success between February and April, losing a few inches and getting down to 132 (a fleeting 131 on one glorious day at the end of April ...) doing Weight Watchers, the 30 Day Shred, then a combination of Jillian Michaels Burn Fat Boost Metabolism and No More Trouble Zones. In May and for about 3/4 of June I foolishly took a hiatus from exercising and paying close attention to calories/points since I was dealing with law school finals, then graduation, then my college reunion, and moving out of my old apartment, but somehow was able to stay around 132 - 133 until about a week or 2 ago. About the third week of June I started doing Ripped in 30 4 days a week and watching my points again, and mid-way through last week I also started double-entering food on MyFitnessPal (averaging 1300 calories, net) to try to get a better balance of macronutrients (having been a carb fiend all my life). I've also done some lifting of heavy weights but not consistently.
After all that, the scale now has me back at 135 lbs, and - what's worse - having gained back all the inches I had lost in my midsection by April. Back at that point my upper abs had decently started to flatten out, but there was still some stubborn chub toward the lower abs ... now both the upper and lower ab areas seem to be sticking out even more than before, such that I almost feel barrel shaped.
I have NO IDEA what I'm doing wrong, and I'm starting to become really depressed. Of course I'm thrilled to be marrying my fiance, but the idea of looking the way I do now on my wedding day - flabby/fleshy/and with too much fat in my face - makes me so sad, and so angry at myself for not having done a better job. Thinking about people taking my picture all day when I hate the way I look, and on a day when I'm supposed to be beautiful ... I just feel like such a failure. I was thin most of my life until the post-college years (I'm 27 now), and for a brief period when I was 23/24 I managed to get down to 125 again before gaining it all back. I just want to feel like myself again.
I'm sorry this got so long, I guess there isn't really anyone I can talk to about this who understands. Any advice would be really welcome. Thanks, ladies.
ETA: I'm currently studying for the bar exam, which is in two weeks, in case that's relevant.
