Dear Practo user, greetings from Chennai! How old are you? You need to immediately consult a psychiatric doctor to rule out any underlying serious heart conditions and establish whether the chest pains are purely stress related.
It appears like stress reaction due to prolonging family issues and your struggle to adjust to the stress situations.
Next Steps
See a psychiatric doctor who would rule out physical health issues and can give you anti anxiety medications which can help you in relaxing quickly and also counselling.
Health Tips
Practice stress management. Deep breathing or abdominal breathing , body scan, yoga meditation etc
