It sounds like you are going through a challenging time with stress, memory, concentration, anxiety, and chest pain, which can be distressing. These symptoms may be interconnected and could benefit from a thorough evaluation by a doctor, especially a psychiatrist or a cardiologist, to rule out any underlying conditions and to provide appropriate treatment.

What you can do now:

• Try to manage stress with relaxation techniques such as deep breathing, meditation, or gentle yoga, which can help reduce anxiety and improve focus.
• Maintain a balanced diet rich in nutrients that support brain and heart health; including Indian staples like millets, dals, fresh vegetables, and fruits can be beneficial.
• Avoid stimulants like excessive caffeine and alcohol, which may worsen anxiety and chest discomfort.
• Keep a symptom diary noting when chest pain occurs, its intensity, and any triggers, and seek immediate medical help if chest pain is severe, persistent, or associated with shortness of breath or dizziness.
• Schedule an appointment with a psychiatrist for anxiety and memory concerns and a cardiologist to evaluate chest pain and rule out heart-related issues.
