I came here to post about this myself. When I was writing, this post came up in the similar posts area.
I have noticed when I have visible weight loss in the course of a couple of days, I get unaccountably angry and sad. It’s really different than other times I’m angry or sad. I get really irritable and get in stupid arguements that I never would otherwise. I have learned that I just need to back away from humanity for a day or so when that happens.
My gut feeling is that it is because I was so unhappy while gaining the weight that it is making me angry when it comes up. I was choking down my rage when I gained the weight. I’m wondering if there is some sort of hormone or something that is released in the weight loss process that makes me feel this way. I’m not sure if that is possible.
This isn’t something that happens all the time, but it’s when I get the big “whoosh” in weight loss. I just lost a lot of weight around my waist, to the point where it feels like I am a different person. I’m very angry and sad today. I know that tomorrow I will probably feel back to normal, and then next week I’ll lose another bunch of weight and feel angry again.
I couldn’t find any information about this online, just a lot of articles about people being depressed after weight loss because it didn’t magically solve their problems. The weight loss did solve a lot of my problems though, and I’m really happy about it. Just not when it’s happening. It seems like it’s physiological, not psychological.
