While I'm losing weight I'm also trying to understand why I became overweight in the first place. I was reading a book called 'fat is a feminist issue' and it's basically about support groups for binge/over eaters and really understanding why we do these things.
Some of them that come to mind. Like:
Fat as protection (against unwanted sexual attention/abuse)
Holding being thin on a pedestal. I've always had it in my head that when I'm thin that everything will be ok. I know that might not make much sense but for me getting closer to my goal weight is making me think about every aspect of my life. I'm scared that if I get there it won't be what I imagined. So I'm trying to be more realistic about this and put effort into other areas so that I'll be mentally and physically healthy.
Being physically smaller, feeling like you have less presence
I don't know if any of these reasons resonate with you but I guess there's no harm in thinking about it a bit more.
I agree with what others posted too and well done so far, you're doing great and you can keep doing it!
