If you're struggling with panic attacks or overwhelming awareness of existence, I strongly recommend seeking help from a qualified mental health professional who can assess your situation and provide appropriate support and guidance.
That being said, some potential factors that may contribute to your experience could include:
Anxiety: Anxiety disorders can lead to a heightened sense of awareness, making you more attuned to bodily sensations and emotions, including the sense of existence. This hypersensitivity can contribute to panic attacks.
Existential or philosophical concerns: Deep philosophical thoughts about existence and the meaning of life can sometimes trigger anxiety and existential crises, leading to panic attacks.
Stress and Life Changes: Major life changes, stressful events, or unresolved emotional issues can trigger anxiety and panic attacks, amplifying your sense of awareness and making you more susceptible to overwhelming thoughts.
Sensory Overload: Sensory overload can occur when your mind and senses become overwhelmed by too much stimuli, leading to heightened awareness and increased stress.
Health Conditions: Certain medical conditions, such as thyroid problems or heart conditions, can cause physical symptoms that may be mistaken for anxiety or panic attacks, contributing to the overall feeling of heightened awareness.
Remember, seeking professional help is crucial in understanding the underlying causes of your symptoms and receiving appropriate support and treatment. A mental health professional can work with you to develop coping strategies, address any underlying issues, and provide guidance for managing panic attacks and anxiety effectively. Don't hesitate to reach out for support, as addressing these issues can lead to improved overall well-being and quality of life.
