It started when I was 17 years old. I never had any real problems with health or huge fears. One day they just hit me. When it started it felt like I couldn't take full breath, as if no matter how hard I tried to breath or how many breaths I took, I just couldn't get a 'full' breath. Then I noticed a nervous sort of burning sensation/nausea and than my throat felt really tight and it began to be difficult to swallow. I thought I was going to die. It was horrible. As time went on the got worse, and sometimes my face and nose would get numb from having to yawn so much(it was the only way I felt I could take a 'full' breath). I would get light headed and I felt like I was really going to die.
NONE of this occurred until I was prescribed "Paxil" for anxiety when I really felt like I didn't have any anxiety, but the doctor said it was supposed to help depression too. After a year of taking it off and on I finally removed myself from it and I kid you not, a few months later I suffered my first bout with anxiety/panic attacks. I've always wandered if that med is what helped cause all of this for me.
It took a few years for me to start battling it on my own. I just decided that if it was going to kill me then I didn't care because dieing from it would be better than living with it. However, it never killed me. I began to learn how to fight them mentally when they start so that they don't get too bad. However, that can rob you of some of your abilities to be emotional. Any extreme emotion can bring you a panic attack. Even being really happy and excited about something can trigger them, so to fight them you do have to learn to 'numb' your brain a bit. I'd be lying to you if I said that it doesn't change who you are socially, mentally, and physically.
After having the upper hand on my panic attack issues for over ten years they have returned with a whole new bag of tricks to try and destroy my mind. I now get numbness in my left arm and cold finger tips with an odd tingling sensation in my chest(near my heart) which makes me fear that it's a heart attack. I also get very light headed and dizzy, and I suffer random migraine-like headaches, I'm more sensitive to light, It's become more difficult to create tears in my eyes and my visions a bit blurred in general, yet I test just fine at the doctor on everything from my heart (ekg), my vision/eyes, to even my blood work being clear and clean.
I'm working very hard right now to get myself in tip top physical condition. I'll see if that changes anything. After that, though, I'll just have to take life and my panic attacks as it comes.
