Panic Attacks

Is there any way to describe the horror of panic attacks?  Out of the blue I'm hit again. Almost 2 years to the month. Dr. says some people have genes disposed to anxiety and therefore panic attacks.  Well, that's not nice to know, though I am a sensitive, nervous and anxious person. Getting old sucks. Paralyzed with a meltdown of the  body is impossible to understand. On to my med, Lexapro, hoping it will do the job again. Life since Christmas was already horrible and then these episodes of more horror. Someone with connections to the Divine, please intercede for me!!!!!!!!!!
