Priyanka, being nerodivergent does NOT mean you cannot learn things. In fact, it very often means quite the reverse. History is replete with neurodivergent people we now consider to be geniuses. Michael Angelo is believed to have been. We know that Thomas Edison was almost certainly on the Autism Spectrum. The list includes, Steve Jobs, Charles Darwin, Alan Turing, Albert Einstein, Steven Hawkings, Emily Dickenson, Abraham Lincoln, Bill Gates, Henry Ford, Richard Branson, Vincent Van Gogh, Sir Isaac Newton, James Dyson, Tim Burton, Nikola Tesla, and many many more.
Your own description of your distractability and that people tell you "if you focus you can learn/do anything" sounds a lot like how my son's ADHD presents. His teachers and counselors always said he's brilliant. His friends think he's a genius. Since he was 15 until he graduated from the county EMS academy, he was the CEO of a game-developer company and remains the company's game-engine designer. He graduated from high school (that's grade 12) last June with honors and all his EMT certifications. He's one of the youngest working EMTs in our county's history – and his FTEP (field trainer) and coworkers seem to think he's a stellar EMT. Everyone who knows him thinks he's amazing.
He is kind and empathetic. He loves to be of help. He's loyal and honorable. He's strong and dependable.
He also was and is always struggling with his distractability. He struggles to break his hyper-focus too. That's another element of his ADHD – he gets hyper-focused on something and may not break from it until he makes himself ill. He's prone to blame himself and find fault with himself where no blame or fault exists.
He is all those things at once together – perhaps BECAUSE he is neurodivergent.
I strongly encourage you to get yourself tested. And, if you're shown to be some aspect of neurodivergent, I'm sure you will find counseling and developmental ways to deal with it in Germany. I mean, if we have those things here in the States, I cannot imagine they not only exist in Germany, but are probably more effectively managed than what we're doing here in America.
