of course you're not alone! we all struggle with it. (ok not WE ALL- but sooo many of us)
the thing is it's different for everyone. there are a million variables. how long have you been overweight factors in because if it's been pretty much your whole life (like me), you adjust and it's more your "normal". i was more freaked out and NOTICED more, losing 30 lbs, than i ever obsessed about being fat. lol. also, HOW big. are you so big you can't fit into airplane seats or theme park rides? uncomfortable in a regular car? are you outgrowing all your clothes so you are uncomfortable on a daily basis because your clothes don't fit right? are you just overweight, or are you really out of shape? i can speedwalk uphill on a treadmill for 45 minutes and feel great - but to look at me you wouldn't know that. i usually kick skinny girls' butts when it comes to something physical. i am overweight, but actually very strong and healthy. do you "hate" the fat because you hate fat people, and you hate yourself for being fat? or do you just notice because it's not "normal" for you? there are a lot of factors.
but in general, no, i don't obsess about it too much - i am really trying, but the last couple weeks, i've been lucky to maintain. we have had some issues come up that have required more of my attention. BUT - my house is clean, tricky finances have been successfully managed, i've had some great time with friends/family, and most of all, my potentially adhd son is getting the best of ME, because i've been spending that workout time researching, reaching out to people, learning as much as i can to help him.
it's all about your focus and your priorities. a person only has so much energy to think about things. some have the "normal" everyday routine stuff down to a thoughtless habit, so other things take precedence in their thoughts. myself, i have to work really hard at the basic home maker stuff, and i work full time, AND i have these issues with my son at school right now, so i don't have much time to think about my weight. i am still watching what i eat and i'm doing "ok", but i don't have that INTENSE focus i really need to lose the weight as i did before. and i'm not being too hard on myself about it, because i have been this way my whole life. and quite honestly, i don't feel the need to apologize for it because right now i am 100% comfortable with my son's issues being my first priority.
ETA--
if you're talking about looking in the mirror every day and bemoaning my disgusting state - no, i don't really do that. i feel that would be ignorant, because it's really counter productive and harmful. i love myself too much, and i have way too much going for me to put myself down, obsess over a couple rolls or jiggles. i have waaay too much to be thankful for in my life. and if i had the time to obsess over it like that, i would have the time to devote to REALLY getting serious and losing it. that is exactly how i look at it.
if you are spending that much time "hating" yourself, you have time to fix it. it's simple math. calories = weight. burn more of them than you take in. right? that's the reality. if you are putting undue pressure on yourself, expecting "magic" results, then yes, you're going to be miserable and stay miserable. talk to the people that are helping you, at ww, pt. maybe they can help you have more realistic expectations, if it's bothering you this much.
