I'm also sensitive to people trying to put me in a caregiver role (which is what I see whiny, won't grow up, cling ons doing). Unless you're an injured frightened animal or small lost child, I really don't like it.
I generally hate my focus being shifted by other people making demands on my attention (for no good reason) when I'm concentrating. I separate myself from others bc I don't trust them to control themselves/stay quiet. Being around another introvert who 'gets it' and we luxuriate together in comfortable silence is awesome :)
I think I'm more sensitive to sound than most. Just the tv or music at home on very loud is painful to me. I'm always scrambling to get the volume down in those overly loud action scenes in movies. I like quiet.
