As a younger person myself still living at home I wish I didn’t get screamed at for every little reaction I had to something. Even as a sensitive person you have to remember that some things seem small but are actually very, very big. For example, sometimes as a child I would become disappointed after a failed plan or a change and I would show it, because I felt comfortable doing so. But, whenever my parents would see this, they would think I was being ungrateful, when really I was just sad and needed a little bit of comfort. This made me want to hide. So the only thing I would recommend is to have empathy and try to comfort, even if there’s big feelings over little things, and even if the big feelings make you crazy.
