Dealing with family pressures

I dont have any pressure to lose weight. I do *gently* encourage my sister to join me on my weight loss journey several times a week. I dont ask her how much she weighs but I really do want her to lose weight before she kills herself.

I've spent years....it's only recently I was brave enough to tell them, Look, the more you pressure me, the less I want to lose weight. They turned it from something healthful I want to do to something that, if I do, is 'them' winning. Totally illogical, but it felt like that. If I lost weight, they had won something (imposed their will on me) and I had actually lost - not weight, but sovereignty over my own person.

Every unhealthy thing I did was a 'victory' over them. Every dessert I ate was a 'victory'. Every chocolate bar I sneaked by them was a 'victory'. Every time I didn't work out, despite their urging, was a 'victory'. Once, my family member scolded me for having bread with butter. In response, I literally ate bread and butter until I puked.

It's only now, that I've fully internalized the desire to become healthier - for MYSELF, my OWN decision - that I am really turning the corner. (MFP has really really helped with this, with the awesome, non-judgmental community here). And now, they seem to understand (though I have to remind them forcefully now and again) and are actually being really supportive. Actually my problem would be to keep them from being 'too' supportive, to the point I resent it. So far, so good.

Have you tried telling your mum this is making you self-conscious? Everyone has a right to good self-esteem, regardless of weight, shape and size. I don't understand pointing someone's weight out to them - they aren't oblivious to it.
