Well, you could TRY to get rid of the problems. MOST you probably have noticed, or have been told, or see in the DSM or in other posts here.
5'11" is actually ABOVE average height, believe it or not. At least in the US. I'm only 6'1". So I am only 2" larger than you are. Are there people a LOT taller than I am? YEP, OF COURSE! Are there a lot of adult men shorter than you? CERTAINLY! And many women that are taller than you are probably wearing high heels or platforms. Are there women taller than I am? Certainly. I don't think they are that common though. And yeah, there is a cluster of women that are around my height. C'est la vie.
But there IS an advantage to being so "short". I have to duck in some places, and places like planes can be problematic. YOU will have less of a problem. AND, I think taller people will tend to have more back problems. .
Frankly, unless you live, or work, in an area with a lot of people that are taller than you, I don't see why you are insecure. Women that are taller than you, because of heels, may consider different shoes, or get rid of them.
