Are You an Overthinker? - Sharon Martin Counseling & Personal Growth Overthinking is common among anxious, perfectionists. It is obsessive thinking or ruminating. People who overthink feel like their brains won’t turn off.
When we feel fear (about ourselves or otherwise) and we run from the fear, it only allows the fear to grow bigger. Using the DBT "opposite action" skill can help us face our fears and let go of that fear. -from Tara Brach's first book, Radical Acceptance
