If you are a victim of past abuse then there is a good chance you are dealing with PTSD. What you are describing sounds like more than a panic attack. I am very concerned for you.

How long have these episodes been going on for, and have you ever talked to a doctor about them? No one here can diagnose you, or tell you with any degree of certainty what you are suffering from. Only a medical professional can do that.

This isn't something that is going to go away on its own. Please take care of yourself.
