Thanks for your question on Health Care Magic.
I can understand your situation and problem.
No, this kind of sudden stoppage of respiration is not seen in
asthma.
By your history and description, possibility of
stress and
anxiety related symptoms is more along with asthma.
Actually stress, anxiety worsen asthma.
So apart from inhalers, you should
consult psychiatrist and get done counseling sessions.
Try to identify stressor in your life and start working on its solution.
You may need anxiolytic drugs too.
So avoid stress and tension, be relax and calm.
Don't worry, you will be alright.
Hope I have solved your query.
I will be happy to help you further.
Wish you good health. Thanks.
