I have synesthesia, and it's because my brain is wired differently (spatial, days of the week are colored and numbers have personalities if you're wondering).
I don't think things like dyslexia is a disability, however. It makes reading harder, but one retains verbal information easily and more accessible then most reading. My husband has it and he can remember conversations from 20 years ago, or something he learned at 5 he can still repeat the instructions. It is simply a different way to process information.
I agree, the so-called disabilities give space to other abilities. My best friend has a strong form of dyslexia, and I gave up correcting her. I was her editor when she wanted to publish a novel. It took us a lot of time to mold her imagination and story telling qualities into a document, ready to send out to publishers. And you know what? She did it. She managed to get her book published.
She had an iron discipline to keep on going and going. I learned a lot from her. Her book was her proof to the world that she wasn't mentally retarded (as was assumed when she was a little girl), just dyslexia. She is great at building up characters, storylines, and imaginary worlds.
She lacked knowledge of grammar and lexicon. But she had me, a former language teacher. I admired her and at the same time, I could laugh at her weird sentences. Often the product of overcompensation. She tried too hard. I gave back a sentence and asked her to rephrase it in her own words and most of the time when she just spoke the words, there was the perfect sentence.
I also have to mention that she has always been a natural astral traveler since childhood. While we were working on her book, she started astral traveling to the world of her imagination. She began interviewing the characters from her book. These experiences gave depth and more logic to the stories. Please don't ask me how these things work.
Later in time, she finished a degree in web design. She is great at coding.
Conclusion: don't lament all the things you can't do, but discover the other possibilities within you that make you special.
Edit: My dyslexic friend has a phenomenal memory. I often joke that she is my extended memory.
