Hola Daniela,
I can so very much relate to this. Beautiful write up! :<)
Have you ever looked into hypersensitivity? Or being ( a ) highly sensitive (person)?
As you are aware of, I am working on some books centered around a character titled Hypersensitivosaurus.
It was only recently though that I discovered some books on 'high sensitivity' and I now realize that that might be even more me than just introverted. I can be extremely social but yeah social situations often tire me loads and I need plenty of time to recover.
Now I'm not sure if introverts are often highly sensitive or whether the mix of high sensitivity and introvertedness is even more powerful ;<)
Un grande abrazo desde Portugal,
Vincent
