I'm 5'6" and since about the age of 11 or 12 (when I started getting bullied seriously due to my height) I'll occasionally feel really down and depressed.
I've been told repeatedly that other short men have been successful in life and that I should focus on the positive aspects. But this is neither useful advice nor is it reassuring. Successful short men tend to be talented (Danny Devito for example, is a talented actor and a funny dude). The "focus on the positives" doesn't really make me feel any better since those positive aspects won't matter when I'll be blindly judged on my height, whether it be from a potential partner or by an employer. I have worked and do work on improving myself (I dress nicely, go to the gym, make efforts to be interesting, am well groomed , am confident around others etc etc), however this only buys me temporary happiness in being proud of my achievements or whatever when I remember that it's how long I am that really determines whether someone will date me or not (for example).
Something else that does nothing to help is the fact that the only opinions that I've seen women hold towards shorter men are those which are very negative. One example is a post shared saying something along the lines of "every girls deserves a tall boyfriend" which got loads of likes, clearly implying that every girl deserves more than a just short guy (height = worth, lack of height = lack of worth). Another example is when this girl and a guy who's in charge of the organisation I volunteer for both agreed that she shouldn't date this guy because he wasn't tall enough for her. They spoke about him with such little respect, simply dismissing him as an option despite how nicely she had previously described him. Another is the multitude of women who say that dating a short man (a man the same height as them) only has disadvantages: they'll never get to stand on their tiptoes to kiss them, they'll never be able to wear high heels etc, and that these disadvantages have a huge sway on whether they date or not.
I feel as though no matter what I do, I'll never be able to be happy with being short and that as I grow older (and as height becomes more important) that these periods of lowered self worth and hopelessness will only become more frequent and more severe.
