<human>: In a bit over a year, I've lost 25lbs, going from 150 to 125. Not a big change to most of you, but necessary. I've altered my diet, I exercise, I drink water, I have more muscle tone than I ever have in my life, I'm healthy. It's supposed to be a good change, right? Then why do I feel like everything I say can be taken as an insult? Why am I paranoid ALL THE TIME? Why do I feel that my friends suddenly dislike me, are possibly avoiding me? That my boyfriend is less interested in me? That I'M less interested in me? I was far more confident at 140lbs than now, at my goal.

Once someone said (regarding a mutual friend who had lost weight), "I miss the fat/happy version of him, the skinny version's a dick." Is there truth in that? Or is it all relative somehow? And what the fuck?

Can you provide a brief overview of the text?
<bot>: Does anyone else feel like the chemicals in their brain haven't gotten used to their new weight, and are going haywire?
