Life may finally seem to be going well. Work is stable, relationships are healthy and everything appears calm. Yet some people still can't shake the feeling that something bad is just around the corner. Instead of enjoying good news, they immediately wonder how long it will last. A promotion brings excitement, but also fears of failure. A happy relationship is followed by worries that it will suddenly end. This feeling is often described as waiting for "the other shoe to drop." Psychology says this mindset is more common than many people realize and is not simply a sign of negativity.
Research suggests it often reflects how the brain responds to uncertainty, past experiences and perceived threats. Several well-established psychological theories help explain why some individuals struggle to relax even when life is going smoothly.
