Hi! From the description you have given to us, you seem to be apparently suffering from an Anxiety disorder like Panic disorder. However the final diagnosis can be made only after a detailed assessment by a psychiatrist
. After the assessment, you maybe started on either psychotherapy
or behavioral therapy
(CBT, Relaxation techniques
) or drugs to improve the symptoms. But all said, you should surely visit a Psychiatrist.
All said, believe me that its not a serious condition and should improve with proper treatment. Keep the faith and you should be fine.
