Security Blankets

I'm supposed to be finishing up an English paper and a take home test for Pre-Calc, but that's just not happening right now. Soooo...I figured I should get something out of my head that's been percolating and marinating for a few days now.
Is my obesity a security blanket? I'm not sure what quite cued this in my head, but...Is it? I was thinking the other day, and while I'm really hoping to get healthier when I get down to AZ...I'm not sure I'm all that enthused about losing weight. On the other hand, no matter how much I try to downplay it the fact is that being overweight makes me feel hideous. So I guess the question is...do I *WANT* to be hideous? Is that one of the reasons I haven't lost the weight?
But when I look at it from another angle I wonder something else ENTIRELY. Yes, being fat makes me feel hideous...but it wasn't until I tipped over into the "obese" category (from the merely "overweight" one) that I started getting hit on. I wasn't treated as sexually desirable until I got fat, or, at least, not blatantly so. Perhaps there were those who thought I was attractive when I was skinny, but they never said anything. So am I fat because of vanity?
I don't quite understand this weird ambivalence about weight loss in my head. Because it's like a teeter-totter "Feel ugly, want to lose weight. Don't want to lose weight, it makes me nervous. Lose weight, people think I'm a loser. Don't lose weight,...for what reason?" I just don't understand myself.
I wondered if I gained some of the weight because of the rape. Was I gaining weight to try and make the husband I was still "in love" with back off? I just don't know. I really really don't know.
There's a third hand too, and that third hand has a lot to do with my temper. Am I staying fat to spite the people who have a problem with my weight? Am I staying fat to punish my mother for all of her well-intentioned and hurtful advice and comments over the years? Am I just digging my heels in because GODDAMNIT I shouldn't have to change to make you happy? Do I want those bitches who make snarky comments about me and my eating habits (snarky and inaccurate) to have to have my fat ass inflicted on their poor skinny-ass psyches? I don't fucking know.
It's times like these where I really feel the need for health insurance and a mental health professional. I mean, I do a LOT for myself. But I don't know if I can psychoanalyze myself out of this one. I want to be healthy, I want to be fit. I'm tired of being tired, and I thinking losing weight would help that. I don't know if I'm keeping the weight on out of stubbornness, fear, or vanity. I don't think I can get as healthy as I want if I can't figure this out. Which is frustrating. SO FUCKING FRUSTRATING.
