Panic disorder is: one POSSIBILITY. Please see your doc to rule out medical conditions and then a mental health professional. Try not to use medication only but learn some strategies for stress management. Peace and good health.

Possibly: One cannot diagnose someone without knowing their history, both mental and physical. Also, need to know how you are crying. Is it a situation in which your lungs are working hard. I think you need to consult someone who can gather the necessary information to help you with a definitive answer. You might want to start with your primary care.
