" Big feelings. HSPs process information more deeply, including emotional information. For example, listening to a girlfriend share her troubles can make nonsensitive friends feel just fine but can be completely overwhelming for HSPs. And HSPs can feel overwhelmed by their own emotions. Sorrow, joy, fatigue, anxiety—there’s no such thing as a little bit sad or a little bit happy or a little bit tired. HSPs don’t feel things halfway. "
