You feel a twinge in your chest. Immediately, your mind jumps to heart attack. You Google your symptoms—big mistake. The results terrify you. You call your doctor, get checked out, and they say everything’s fine. You feel relief. For maybe a day. Maybe just hours. Then a new sensation appears, or doubt creeps back in about whether that last test was thorough enough. The cycle starts again.
This is the hallmark of illness anxiety disorder and somatic symptom disorder. Reassurance feels like the solution, but it’s actually feeding the problem. Every time you seek confirmation that you’re okay—whether from doctors, loved ones, or the internet—you’re teaching your brain that these fears require urgent attention. You’re reinforcing the false alarm system.
The same goes for body checking. When you constantly monitor your heart rate, examine your skin, or prod at areas that feel off, you’re amplifying your awareness of normal sensations. You’re often creating new discomfort through the checking itself. Your brain interprets this vigilance as evidence that there must be real danger lurking.
Treatment doesn’t work by convincing you that your fears are irrational. It works by teaching you to sit with uncertainty without needing to resolve it through checking or reassurance. That’s where real freedom lives—in the space between the fear and the compulsion.
