Yes, I suffered from Panic Disorder for over 10 long years. These symptoms are symptoms of Panic Disorder, not of a crazy person or someone who is going to die. I assure you I have experienced this at first hand. Anxiety, Panic Disorder is distinguished by prolonged and repeated attacks with debilitating anxiety between attacks. You begin to withdraw avoiding social encounters in fear of another attack.
An encounter with a panic attack does not mean you now have Panic Disorder unless you experience countless times of anxiety in between. Panic attacks may last a few minutes or up to a few hours. Your body physically becomes exhausted from the emotional turmoil and restores itself to normal human behavior. It's important to feel safe in a secure atmosphere or environment, in-case depression sets in after the attack softly simmer. Furthermore, you need to be surrounded around someone who truly loves and understand you due to constant worry and fear. Unforeseen panic, leads to more panic so stay calm. Panic can feel completely devastating with a force of doom. Panic may be managed with herbal treatment, therapy, or medication.
In my experience, have a good support group system, confide in those closest to you, for you need not worry about judgment. Many of us suffer from anxiety if you or anyone you know suffers from any of these symptoms; help is beneficial to obtaining a normal productive healthy lifestyle. My life was a completely controlled lifestyle at one point.
My determination to overcome suffering from anxiety and panic disorder was an endless valuable journey of research, medication, herbal remedies, meditation, yoga, and counseling. My journey has not ended so I can't say my anxiety and stress have completely disappeared; however, my perseverance and knowledge have intellectually given me just the medicine. Acceptance is the answer: it relieves symptoms of anxiety. I no longer fear any anxiety or panic coming upon, because I have a keen sense of exactly what is happening. Accepting this reduces what-ifs: in turn, it no longer has room for growth, however, you do. Confronting your fears eliminates them, little by little. Currently, I have so much control that when a thought windless in, I simply allow it, gracefully accepting it. For example: if I think I am crazy, I accept it, so what if I am crazy, many of us are, if I think I am dying, I say well if I do die I was fortunate to have lived, these techniques have brought great relief and comfort.
Anxiety symptoms are very frightening and real, do not tell someone to snap out of it, encourage and support the person suffering from panic. Imagine thinking your dying or going crazy it can be a very scary and confusing experience for someone suffering from panic. Medication may be helpful, but stagnates the problem in reality you need to talk to release anxiety; medication provides a hidden cover-up the illusion. Eventually, it seeps out and depression set in, so take care of the situation at the root. Most importantly listen to your body it speaks silently, but if you don't listen watch it scream.
