Anxiety why me...why not

Right now I’m suffering from an anxiety attack and I don’t know how it got this far.

I was sitting watching home alone with my grandchildren and I began to feel as if I was not breathing right and bam it’s on a popping. I’m not sure how long this one will last or if I will survive it, because all I can think about is death and dying suddenly, how long will it last. 

I have not had a drink in two days could that have anything to do with it, I’m not sure but reading about alcohol withdrawal symptoms only made it worse, feels like I’m smothering under covers and my nostrils have stopped up I’m not survif it’s my breathing or just the anxiety or both. Not to mention the tingling feeling I get in my hands, I checked my blood pressure three times and it went down the last time, but my heart rate was still above one hundred. 

I have a hard time accepting death, I know it’s gone come but it’s my greatest fear, the fear of death stops me in my tracks and now I have to walk and pace back and forth until I’m not so anxious.

Imma head outside again to suck in some fresh air and hopefully it will work and my nerves will calm down because when I’m like this I can’t sleep and I’m afraid of dying in my sleep in my bed alone and no one will know I’m sick...
