A highly sensitive person is someone who feels things very deeply and strongly. Think of it like being a superhero with extra spider-sense, but instead of spiders, they feel all sorts of emotions and sensations very intensely. For example, a loud noise that might not bother someone else could feel incredibly overwhelming and scary to a highly sensitive person.
These types of people often like to take their time to process and think through situations before reacting. They might also have a hard time in crowds or with lots of stimulation because it can all feel like too much to them.
It's important to remember that being a highly sensitive person is a good thing, though! These people tend to be very empathetic and caring towards others. It just means that they need to be aware of their sensitivities and take extra care to make sure they're not overwhelmed by their surroundings.
