Hey, man, no need to apologize. You seem to have a lot going on in your mind. Feel free to PM me if you want to talk about it or just vent.
I think most of us understand the feeling you're describing here. Just remember that no one is perfect. For this one trait of yourself, height, there's even this extreme surgery that can help alleviate that psychological pain to some degree. There might be even better methods when we're older. It could be one, but it's not a hopeless matter.
I am almost 25, since last 5 years there was no one singel day that i didnt think about how my live would looking if i was at least 10 cm taller. All the things that i have missed... I can not get it out of my head. Despite what I have achieved in recent years, i remember no day that i was really happy. I fought to every adversity every insult, humiliation, rejections and i thought it does not effect me..
I know what some of those thoughts are like. But you need to remember no one is dealt a perfect hand in life. It could always have been worse, and it can
always become even worse. I know this doesn't cheer someone up. However, it's something you can tell yourself during the worst days.
I am guessing you are in the very short range: sub 160cm to 164cm.
What if your problem was not that you lacked 10cm, but that you realistically needed to be more intelligent to do what you
really want to do in life? Or something similar to that. Currently, making ourselves significantly more intelligent is outside of the realm of possibility. There are too many things in life that limit us, and for many of those, there's not a lot, if anything, that we can do about them. There are areas of STEM that I would love to touch and really learn, but I am just not intelligent enough for them. There's nothing I can do about it --- not even any type of surgery. This is not to say bad realities are set in stone forever. However, we have to focus on the present. I don't know where I'm going with this, but I was just hoping that offering some perspective, in the way I see things, at least, could help in some way.
If you're not actually short, I think you just need some form of counseling or help to deal with those feelings of yours. It doesn't need to be a therapist. It could be just a close friend you've known for years.
But anyway, thanks for sharing the insight you came to develop through your own personal experiences. That's unique to you.
