how having anxiety feels like?

I am having a headache, it kills me.as long as my husband mention preparing for a job interview,i will be overwhelmed.i hate to talk about these things. It makes me nervous and uncomfortable, I am afraid of the unknown future,I don't know if I am gonna be ok if all things out of my control ,if i am not be able to handle this.I am getting freak out ,even the word job can make me overwhelmed.I can not stand it any more.

It feels like there are  bees in my ears ,I can not sleep well.I stay up late in the evening I even don't know what i think about,it just happens.the more I want to get asleep the more I awake.

This afternoon, I tried mindfulness and yoga，then l feel much better.I guess I don't like to be pushed away,to a place where i can't imagine,what people I will meet,where I will be going.but i believe I will be ok ,so face what it is and see what will happen, accept the fact and do what I can do.may I be happy.
