Based on your symptoms and the information provided, it seems that you may be experiencing a combination of autonomic nervous system (ANS) dysfunction and anxiety-related issues. The autonomic nervous system is responsible for regulating involuntary bodily functions, including heart rate, digestion, and respiratory rate. It consists of two main branches: the sympathetic nervous system, which prepares the body for 'fight or flight' responses, and the parasympathetic nervous system, which promotes 'rest and digest' functions.

Your symptoms of dizziness, chest tightness, difficulty breathing, rapid heartbeat, and occasional numbness in your hands can indeed be associated with autonomic nervous system disorders. These symptoms may also be exacerbated by anxiety, especially if you are prone to overthinking and nervousness. Anxiety can trigger the sympathetic nervous system, leading to physical symptoms such as palpitations, shortness of breath, and gastrointestinal discomfort.

Given that you have already consulted with gastroenterology and cardiology, and they have ruled out significant issues, it may be beneficial to explore the possibility of anxiety or panic disorder, which can manifest with similar physical symptoms. Over-breathing (hyperventilation) is a common response to anxiety and can lead to feelings of lightheadedness, tingling in the extremities, and chest discomfort.

To address your concerns, I recommend the following steps:
1. Consult a Mental Health Professional: Since you mentioned being prone to anxiety and overthinking, seeing a psychologist or psychiatrist could be beneficial. They can help you develop coping strategies for managing anxiety and may suggest cognitive-behavioral therapy (CBT), which is effective for anxiety disorders.

2. Consider a Neurologist Consultation: If your symptoms persist or worsen, it may be worthwhile to consult a neurologist. They can evaluate for any underlying neurological conditions that might be contributing to your symptoms.

3. Lifestyle Modifications: Incorporating stress-reduction techniques into your daily routine can be very helpful. Practices such as mindfulness meditation, yoga, and deep-breathing exercises can help activate the parasympathetic nervous system, promoting relaxation and reducing anxiety.

4. Regular Physical Activity: Engaging in regular exercise can help improve your overall well-being and reduce anxiety. Exercise releases endorphins, which are natural mood lifters.

5. Monitor Your Diet: Since you have gastrointestinal symptoms, consider keeping a food diary to identify any potential triggers. Eating smaller, more frequent meals and avoiding caffeine and alcohol may also help.

6. Medication: If your symptoms are significantly impacting your quality of life, discussing medication options with a healthcare provider may be appropriate. Antidepressants or anti-anxiety medications can be effective for managing anxiety symptoms.

7. Follow-Up with Your Primary Care Physician: Regular follow-ups with your primary care physician can help monitor your symptoms and adjust treatment plans as necessary.

In summary, your symptoms could indeed be related to autonomic nervous system dysfunction, potentially exacerbated by anxiety. A multidisciplinary approach involving mental health support, lifestyle changes, and possibly further medical evaluation will likely provide the best outcomes for managing your symptoms. Remember, it’s essential to communicate openly with your healthcare providers about all your symptoms and concerns to receive comprehensive care.
