Severe panic attacks suffered, how can i get over it ?

CBT: I would start with a comprehensive psychological evaluation by either a doctoral level clinical psychologist or a psychiatrist. Appropriate treatment planning can be made with you which may include options like cognitive behavioral therapy (cbt) and/or psychotropic medications. Take care.

Tight chest: First step is thorough workup by your family doctor to rule out breathing problems & other medical factors, then if all clear, consult a psychiatrist for further evaluation & management of your anxiety symptoms.
