<human>: Can you provide a brief overview of the text?

Back when I was fat (or, rather, fatter) and wasn't doing anything about it I was rather lax about my appearance. I mean, I didn't particularly like my body or face, but sometimes in the right light I thought, "I'm not so bad!". And I just wasn't bothered in general, you know? I thought, "There's no way I'll lose all that weight anyway, so I better just chill".

Now, when I'm 20 lbs down and am pretty confident that I can reach my goal weight this time, I'm starting to obsess over my looks. It suddenly turned out that attaining the perfect body, in terms of body fat and muscle, is actually possible, and that's amazing, but now I'm focusing way too much on aspects of my looks that are (relatively) immutable. I find myself planning multiple plastic surgeries and invasive cosmetic procedures. Just 10 minutes ago I looked at my legs that aren't perfectly straight (most likely from carrying all that weight around since childhood) and straight up started crying, and I'm not by any means an emotionally unstable person. But not having perfectly straight legs means I will never get to be perfect after all, no matter how hard I try, and in the past I was at peace with this idea. And now, since I'm actually changing something I previously thought to be immutable, I'm not at peace anymore.
<bot>: used to be fat and kinda sorta okay with myself, now hate myself for all the things I actually can't change about my appearance.
