Suggest Treatment To Reduce Weight And Breast Size

I am technically "overweight" if not "obese" due to my height-to-weight ratio, but here's the thing...I'm mostly boob. Looking at myself in the mirror, while I definitely do not look skinny, I do not look particularly 'fat' either...really flabby, but not fat. I just look like I'm all breast, in a way that is totally disproportionate to the rest of my body.

I don't know what to do. I have been both bulimic and anorexic in the past, and I am afraid that if I try to lose weight I will go too far again.

Meanwhile, I have ongoing stomach troubles that leave me exhausted much of the time, and PTSD nightmares whose threat keeps me awake.

My real problem is a lack of exercise, I know that; I have always had a speedy metabolism and rarely get constipated, and am often hungrier than I think is healthy simply as a result of struggling to find things my stomach will actually be willing to digest [the list consists of 'cereal, almond milk and silver noodle soup' so far].

Doctors, I am concerned that my weight will always be determined by this so-called "gift" God gave me. I am the black sheep in a family full of stick-thin people, so no one was able to teach me how to 'wear my size' gracefully...I suffered a lot for my size growing up. I was never overweight per se, not in the sense of being "fat" anyway--I was always a very active kid. I simply "developed" far earlier than most kids my age, and THAT I was teased about. My curves also seriously upset my mother, leaving me with obviously mixed ideas about my body...

Can I even exercise? I love horseback riding, but since fully "filling out" I have yet to get on a horse. I am afraid it would be too uncomfortable.

What do I do? I eat right, and as soon as I feel better I know I will begin exercising again as I love it too much to quit...but how do I keep from being permanently defined by having breasts several sizes too big for my body, and far larger than I feel like I can ever be comfortable with?
