In my early 20s, a psychiatrist told me I had anxiety. I said that I'd heard the word, but I couldn't grasp what it meant, because the feeling was so foreign to me. He said it was the water I swam in, which is why I couldn't see it. Then I saw it, and I could start a growth process I desperately needed.
Sometimes you have to step out of the water, or find someone who can lend you a hand to step out of it.
