What you’re feeling is a deep emotional response rooted in health anxiety and fear of mortality—and it’s far more common than you think. When we see or hear about people our age suffering or dying, it can create an overwhelming sense of vulnerability, as if something terrible could happen to us or our loved ones at any moment. That fear then triggers a fight-or-flight reaction in your body—leading to trembling, headaches, and a strong sense of unease. Seeing your friend unwell can add to this, because it feels close, personal, and terrifying. What you’re going through isn’t weakness—it’s your brain’s way of trying to protect you, even though it’s overreacting to perceived danger. Therapy can help calm these fear pathways through techniques like CBT for health anxiety, exposure therapy, and emotional regulation training. We’ll work on grounding techniques to control your physical symptoms, and slowly help your mind process fear in a more balanced way. You can come out of this and start living without that constant shadow of fear. Take therapy, and you can connect with me on nine two six six seven two six zero six five.
