I am sorry to hear you are experiencing panic attacks. They are terrible, terrible, terrible.which I unfortuntaley know out of experience. I am not on any mediciation, but chose to try to deal with them with the help of my therapist who has diagnosed me with PTSD.
I can tell you a bit how I deal with mine, and perhaps you can find it somewhat helpful.
When they happen, I know that they are panic attacks and will feel terrible.
I try to not fight them, but let them happen and accept that this is how they feel - just very terrible
I check with either my husband or somebody else close, to make sure it is just me panicking and everybody else is just fine
I try to learn what trigger them (darkness is never great for me, especially when I am alone)
My therapist has told me that each panic attack has a beginning, a middle and an end. This helps me to wait it out, like a storm.
I try to distract myself. Moving helps me best.
I have some pills, I can take just in case and knowing that they are there helps a lot. I have never needed them after all.
Last but not least, I think that panic attacks are a delayed reaction. Physically they are what you'd experience when your life felt threatened. Pulse is quick, heartbeat goes up, hormones are released, your muscles are tense; you are ready to attack or flee; but because it is the wrong timing and situation, you only experience the symptoms, the threat is long gone (which for us is unfortunately PE).
I hope you can find a way to deal with your panic attacks. You are not alone, I have them too and don't like them a bit.
Sending you hugs.
