Hello. It sounds like you've been under a great deal of stress, and I can understand how exhausting this must feel.
The symptoms you've described—feeling panicked in small situations, excessive overthinking, emotional exhaustion, irritability, headaches, dizziness, stomach discomfort, chest heaviness, and difficulty breathing—can sometimes be associated with anxiety and prolonged stress. Since you're a research scholar, it's understandable that academic demands may contribute to these feelings, but they shouldn't be ignored, especially if they're affecting your daily life.
In the meantime, try to maintain a regular sleep schedule, take short breaks during work, practice slow breathing or relaxation exercises when you notice yourself becoming overwhelmed, and avoid isolating yourself.
Next Steps
I would recommend consulting a psychologist for a detailed assessment. Therapy can help you identify the patterns that trigger your anxiety, develop healthier coping strategies, and reduce the physical symptoms associated with stress. If your symptoms are severe, persistent, or significantly interfering with your functioning, a consultation with a psychiatrist may also be beneficial to determine whether medication is needed.
