What is the best way to deal with chest pain related to anxiety? i've tried breathing techniques etc. but i can never seem to calm myself down.

Tension and release: One way to induce relaxation is through use of tension and release exercises. Inducing greater than normal tightness in muscles or the diaphragm forces a similar and opposite release of those areas. These r really effective when used with proper breathing. Examples include progressive muscle relaxation and exercises. Recommend seeking instruction from trained a professional like a psychologist.

Anxiety: Talking therapy ranks really high. Cognitive Behavioral therapy or psychotherapy can be effective. Aim for daily exercise, 8 hours of sleep per night & good nutrition w 5 servings of veggies & 4 of fruit per day. Try tai chi, yoga, Qi Gong, progressive muscle relaxation, deep breathing exercises & meditation. Don't isolate - spend time w friends & stay active.
