Sudden feel chest sinks and heart stop.

Hi First of all, you’re not alone in this experience, and I truly understand how scary it must feel when your body reacts this way despite all medical reports being normal. From what you’ve described — chest shock-like feeling, trembling, choking sensation, breathlessness without physical cause — this strongly points toward Panic Attacks and Health Anxiety, which are common manifestations of Anxiety Disorders. When your mind perceives a threat (even unconsciously), your body’s fight-or-flight response gets activated, releasing adrenaline. This causes symptoms like: • Racing or skipped heartbeat • Trembling hands and legs • Feeling of choking or breathlessness • Tightness in the chest • Sensations like “shock” or internal vibrations The fact that all your medical tests are clear and multiple specialists ruled out organic illness is a strong indicator that this is anxiety-driven, not a heart, lung, or neurological issue. This condition is highly treatable with CBT (Cognitive Behavioral Therapy), where you’ll learn how to manage catastrophic thoughts, control physical symptoms, and prevent panic attacks from escalating. Take therapy, and you can connect with me on nine two six six seven two six zero six five.
