How to say I'm re-committing without sounding like I've failed?

Because I don't think I've failed. I'm having some trouble getting back to losing, and I've gained some back over the last few years. I have my reasons. Personally, I'm a lot happier today than I was when I got to my lowest weight (198.9 or so at the end of 2014). When I started mid-2013 I weighed 299.

Currently I weighed in post-vacation at 234.6ish (can't remember the decimal), highest I've been since I was at that point on the way down. I changed jobs at the end of 2014 and while my job is now a lot more active, it's a lot less structured and thus has been an excuse of sorts as to why I haven't been cooking as much as I was before, and haven't been planning my weekly meals as much as I used to (since I used to do that during my work shift and now don't sit at a computer anymore). We also bought a home, moved, had to move out because of a flood from above, and more job changes. It certainly makes it harder for me to focus on my weight loss.

When I started I was absolutely obsessed with learning as much as I could about what works, what doesn't and how to best use those tools to my advantage. I was doing really well with it in my structured environment, but when everything started shifting around a couple years ago I stalled, and over the last year that stall became a gain.

I'm not upset about it, I'm not mad at myself, life happens and I didn't deal with it in the best way to maintain my habits. I know what I need to do, I just need to figure out the best way to build those habits into my new, much more erratic lifestyle. I don't have regular days off, I sometimes only get one day off for 10-12 days of work, and frequently have shifts that start at 10pm half the week, and 6pm some other days. I also travel more now than I used to, and discovered how much I really love craft beer.

Since I started in 2013, I am so much more active than I used to be and I am entirely grateful for that change. Just last week we went to Yellowstone/Grand Teton and didn't shy away from any activities. I did all the short/incredibly steep hikes we could down the canyon walls, around the lakes, climbed on rocks near the waterfalls and did a whitewater rafting trip. It was an amazing trip, and I don't think I could have/would have tried doing any of those things back in 2013.

Anyway, for anyone who is really just starting, know that this is totally possible. I didn't do any crazy things, just walked more, went to the gym 3x a week doing mostly strength training with some cardio (literally no more than like 30-45 minutes each day), and logged everything. I weighed everything, weighed all of my recipes to the gram and then weighed out my portion of that recipe. I haven't been as good about logging and that's the thing I'm working on now, again. Unfortunately (or not?) I know exactly what my problems are, I just have to commit myself to being more diligent about my practices. I would love to have more/new friends either in my boat or even if you're just starting or mid-journey.

tl;dr Lost 100 lbs, gained some back, ready to lose again, looking for more friends!
