Ahh, honey, I agree with ya. You can't be told by someone else, "Okay, now lose weight." You have to really want it for yourself.
But that being said... it sounds like you do. So, what's it gonna take? What's holding you back? Maybe systematically go through your bad behaviours... and think of logical, doable solutions to them?
Example: I tend to stuff my face while sitting in front of the TV despite not being hungry.
Solution: Sit back with a 1.5 Liter bottle of water, and find something to do with my hands. I've been knitting scarves for friends for Christmas, sometimes I draw for my drawing class, etc.
Also, I was telling someone tonight that I couldn't eat a cookie that she offered me. It was a slip of the tongue, I normally just say, "Ahh, no thanks I'm good," but tonight I accidentally said, "Ahh, no, I can't, thanks." Which of course, illicited the "Can't? Why can't you?" question, and I had to go into detail about cutting out wheat and gluten since it has killed my metabolism. Gluten intolerance.
When I'd finished, she kinda shrugged, "Oh, that's cool. I don't think I'd have the willpower to say 'no.'"
And as soon as she said it, I suddenly realized... I haven't eaten a cookie, a muffin, a roll, cake, a donut, or anything with wheat in it since Thanksgiving. (Canadian thanksgiving, so, October 12thish?) In a month, I haven't felt any HUGE desire for any of those things, and I realized... that the thing that's been making me CRAVE those foods... was those foods themselves. And I know, I've heard people say that before, but... I've struggled with weight loss for YEARS, and all I managed to do was put more weight back on. By cutting some things out, but still allowing myself the occasional bit of chocolate, or the occasional bit of.. whatever.. well, it never helped. I always wound up binging on those things once I got a taste for them.
My advice then, I guess... is muster all the will power you've got, and take things a day at a time. Decide (with will, and FORCE, because I
KNOW that you're strong enough...) that tomorrow is going to be a good day. And all day long, think about the fact that today is your day, your first day of being
perfect health-wise, and instead of focusing on feeling deprived and frustrated at saying "no" to the junk you would normally eat, focus on the strength of will, and the positive changes that you're making towards a healthier you.
The best way to make myself turn down a chocolate bar/walk past that vending machine was to think about how depressed and disgusting I'd feel staring at the empty wrapper afterwards, and feeling the taste of the chocolate wash away from my mouth.
Y'know... 147.. that number is just not that far away, chica. There's a 147-lb you at the finish line looking super sexy, and turning mens' heads left right and center, and she's just waiting for ya to get moving.
(And... p.s.? She won't be wearing any "fat clothes".
