even though I'm an adult, I still have a body that seems to be less developed, when we think of adult women we usually think of everything voluptuous, but I'm quite the opposite, I look like a teenager entering puberty...The problem is, I feel less of a woman or I feel like someone underdeveloped or a boy (I don't want to change genders, it's just a feeling, because I don't have many curves or breasts this is associated with masculinity and I've seen many phrases like that )
I don't know how I could use my body for anything, tall women can use it for modeling, stronger women can use it for weightlifting. And how can I accept myself, accept my features?
First of all you have to simply recognize that these are your characteristics before accepting them.
I am particularly short and in every way I tried to tell myself: "come on, I am more or less as tall as the others...", I tried to deny my characteristics and it hurt me to have them.
When I accepted being like this, I understood that it is okay to be as you are in a natural way, I started to love myself and my unique characteristics, because charisma, even physical, is in our individual details that change from person to person.
From the point of view of martial arts, being short could really seem like a disadvantage, but what corresponds to the truth is that you have to learn to enhance your characteristics. Everything has its advantages and disadvantages.
I am short, so for me the clinch (remaining clinging to the opponent's neck) is more difficult and dangerous to perform, so I avoid it, but I have more control to detach myself from the opponent's clinch and therefore I get the upper hand by avoiding it; this is a small part of the martial arts that I do, but it is a good example.
Taller, stronger and more muscular people, yes, think that if they kick me in the head or simply punch me they will kill me, and it is true, the fact is that they never manage to hit me because my technique is superior to theirs (since I do not have much physical strength being short I have to focus only on technique), it is no coincidence that they praise me by saying that I am "too strong" and things like that.
You are not at fault, you have individual characteristics that others do not have. Everyone has their own, see what advantages you have. Apparently the only advantage in martial arts is having the strength that if you hit, the other person dies in just one of your hits, but in reality no one can hit me because I am faster, more reactive and have a superior technique.
I learned that being short I can hit low, and there are more effective techniques for me, etc. Because I learned to APPRECIATE what I could do and not focus on what I could NOT do, but others could.
I hope this little example has been a guide for you. Start to understand the strengths of who you are, stop seeing your difference as a deficit compared to others, your difference is only making you unique. If you know how to manage it, it will make you special.
