Firstly, I want to acknowledge how overwhelming and distressing it can feel to experience anxiety, especially when it intensifies to the point of derealization, pessimism, and depression. These are not uncommon, and you’re not alone, many patients suffer through these symptoms. From what you mentioned you are experiencing anxiety - a state of heightened alertness in response to perceived threats. It’s like your brain is constantly sounding an alarm. When this becomes too intense or prolonged, your mind can struggle to process everything, leading to derealization—a feeling that the world around you is unreal or detached.
This happens because your brain, in trying to protect you, “disconnects” from the overwhelming sensations to reduce emotional overload. It’s not dangerous, but it can feel very unsettling.
When your brain is stuck in an anxious state, it focuses on negative possibilities or outcomes to keep you “prepared for the worst” a defence mechanism of brain. Pessimism makes one unable to see hope or solutions.
Chronic anxiety can exhaust the brain’s resources. Over time, this can lead to depression—a state where you may feel low energy, sadness, or hopelessness.
Biologically, these experiences are linked to imbalances in brain chemicals like serotonin, dopamine, and norepinephrine, which regulate mood and perception. Stress in any form (physical/social/financial)can worsen the symptoms.
While these experiences feel overwhelming and distressing with treatment it’s curable.
