Mentaly caused hearth and breathing problems?

The anger and crying sounds like a stress or anxiety attack. If she's just stopped birth control there is probably a stressful reason behind it. Also, the age and quitting smoking are both very stressful. Quitting smoking (the nicotine withdrawal) can wreak havoc on both the heart rate and breathing. I would recommend her seeing a doctor right away, to make sure that everything is under control. If necessary she can be prescribed drugs to keep her emotions under control, and it's important that a doctor monitor her heart and breathing.
