This is going to be long, and potentially rambly, so please forgive me.
I've never really been a huge "public" person. Sure, I liked to do things with friends back in the day, but I was mostly content with staying in.
I became a little more social when I lost a lot of weight. It might've had something to do with more confidence, but I wasn't without confidence ever before that. I have to say a lot of it had to do with energy gained from the positive changes I had made.
...I set that up to say... when I gained back the 100 pounds I'd lost I was going through some really icky stuff mentally. I NEVER wanted to go out. I was back up at 327 pounds. I felt like a failure. I felt like anyone would see right through my fat clothes into the failure that I was. I didn't want to put myself through that. I didn't even like to go out grocery shopping. I was so low that I -didn't- go out at all for months at a time. I'm not exaggerating. I was a hermit.
I'm going to say here, even though I'm FULLY ashamed of it, that my weight kept me away from my family last Christmas. Yep. It was the first year in my life that I didn't go to Christmas... and it was because I felt like a failure.
That was the lowest point in...my whole life. There. I regret it. I admit it. I allowed myself to think that I was "too fat" to go see my own damned family.

How selfish of me. How thoughtless and consumed. How
wrong!
It wasn't even the being fat that kept me away. It was feeling like I hadn't really accomplished anything. That I wasn't proud of anything I was doing. That I had nothing to show, and nothing good to give. I'm getting upset just remembering how I thought those things about myself.
*deep breath*
I recognized what the problem was, I just wasn't ready to DO anything about it. The unfortunate vicious cycle of it was that I knew that exercising and eating better breed a positivity in me... but I didn't feel good enough about myself in order to exercise and eat better for another four months.
I can't even say what "flipped the switch". Only that one day I saw I was about 5 pounds from my original high weight, and it was as though a portion of my brain screamed at myself "WHAT ARE YOU DOING TO YOURSELF?"
And this is where I am grateful for having lost weight in the past and knowing what it takes: I told myself I would make a couple small changes and no matter what I'd just stick with those. Didn't matter what happened. I would just stick with those small changes.
The first week I began adding in activity, and tracked my food.
Gonna be honest again. It was piddly. Walking 5 minutes a day on the treadmill. Tracking the entire box of Cheez-its that I ate in one sitting. Didn't exactly scream "lifestyle change" to me.
But, I knew what I needed in order to feel good about myself, and that was the positive reinforcement. That meant that every time I did ANYTHING good, I overpraised myself.
That five minute walk? I wanted to throw confetti at the end of it, I was a super marathon runner.
That box of Cheez-its that I ate and
tracked every bite? I might as well have been named Time's Woman of the Year, because of the mental party I had about how successful I was.
That first week I was a changed woman. Well, in some ways. By the end of the week I actually wanted to go out. Now. I didn't want to go out to be seen, but rather I wanted to go grocery shopping so I could make even healthier choices the following week. I still had a purpose. I had a goal.
Before... I hadn't been proud of myself. I was ashamed, and lonely, and depressed.
Now... I'm not going to say I have a perfect track record, but I
created something to be proud of myself for. I'm going to tell you that overpraising myself has become a little bit of a fun project. ANY healthy habit is subject to positive talk.
Did the dishes? I'm a superstar!
Did the laundry? Do a victory dance!
Take the trash out? Put my arms up like I'm winning the Olympics!
And, yes. I'm fully aware of just how ridiculous this sounds. But, it works for me, and I wouldn't have it any other way.
I
like liking myself. People whom I interact with are lucky to speak to me... just in the
same way that I'm lucky to speak to them.
Where did it start? Finding... no...
creating a reason to be proud. Making it foolproof, and catching myself with any negative talking to turn it around. Example: "
I should've done more exercise." Response: "
Psht. Remember when your only exercise was opening the fridge door? Yeah. I remember. This walk was great, and you know it."
I suppose I'm winding down in my thoughts.
TL;DR - I recognized what would make me feel better about myself. And this will vary, but mine was movement and keeping up with the housework to start. I use positive mental self-talk
every day. EVEN WHEN IT SEEMS RIDICULOUS.
