I don't think it's particularly stupid, perhaps it's a language barrier and the words could have been expressed better. What I understood him conveying is a typical height neurosis symptoms. The sense of inferiority and upsetting and self-consciousness and darkness around tall people is typical, perhaps this is a tad more extreme because dgshorty is already 5'10. I don't think he wants his worth to be reflective of his height because he saids "how do you fight [these feelings] back showing a desire to change for the better, and no one wants these stupid mind thoughts, but our mind and neuroticism takes control and we can't control it most of the time. It seems like that's the point of his post, asking for help on how to try to NOT make his worth reflective of his stature. If i could cure height neurosis and dysphoria completely with a pill I would forget about LL
That's it, can't explain better myself
But, just accpet that you will always be shorter than someone. Humans go way further than 220cm height. I suggest that you search for a psicologist and work at it, cause you're not really short, and I got the feeling of what @serilium said. You can get CLL and you will still thing you're short next to other taller guys, and it will always have taller guys, unless you're the tallest human alive.
Just try to accept that you're not a giant, you're a normal human being, and also be aware that too short is bad but too tall is awful too. Even girls don't like really tall dudes, they like a specifc range of height more. Just imagine someone who has 4cm penis, thats short. But you have an average one and you're feeling bad cause there are guys with 28cm one. But dude, 28cm is really freakin weird, imagine now it being 40cm. I know it sounds so stupid, but it's my way of explaining. I'm short and I have the same feeling (although mine is with almost every dude, cause im 5'6) and if I get a HUUUGE CLL I will be max 5'10-6'0, and there are plenty of other 6'0+ guys and some 7'0+.
Try focousing at their details, like: his teeth are yellow, his hair is messy, he doesn't dress well, he's ugly, etc. And focous at your good details like: I'm sxxy, I'm strong, I have abs, I have a cool hair, my clothes are awesome, I'm a nice person, I have a nice jawline, I have glass skin, and so on.
But try going at least once to the psicologist, please.
And yes, I don't want to be noticed anywhere, cause I feel so short, that girls won't even look at me and people will think I'm 15, and that always happen, I struggled talking to patients and my teachers (who are old doctors) never believe I'm their stundent. It's really bad, cause some girls like my appearence, and talk to me at Instagram and at university they see me sitting too ad they think I'm somehow a bit handsome, but when they acctually see that I'm 5'6 I just don't get the attention anymore. And it really sucks having a chance with cute beautiful and nice girls from instagram (from other universities at my city) but knowing that when they see me I will be kind of a catfish, but not about appearence, but I will be just short...
Don't worry, you're not alone, but please get a little hand for a help!
