Geniune question: What should I be expecting?

I’ve never openly talked about this since it’s an awkward question in itself.. Here we go.

I, 18F, am 5’2, and I weight about 175-180 lbs. I’ve been pudgier in my teen years, but I feel like I carry my weight very well. I have yo-yo dieted, actually stuck to it, and dropped it completely.

My question is: If, for a good amount of my life, I have had a larger chest, how much weight should I really be expecting to lose? How will this look on me? Can I achieve things that smaller-chested girls can?

I feel stupid. On top of this all, what are some tips to stick to this for long-term too? What have you all done? I know what the good majority of educated people know about weight loss, I’m talking those small tips that help YOU. Thanks :).
