Do we ever have a good day without anxiety?

I do not know if anyone has read my recent posts but I had a very stressful week last week.  My therapist told me to give it a week to feel better.  I saw her last night.  She said even a person that did not have anxiety would be tired for a while.  I am very hard on myself.  Today I am getting one of my headaches that starts in my neck and goes up my back of my head  and then around my head.  I feel like there is a brick on my chest and that I could sleep for an 100 years.  A lot of my friends who donot have anxiety are starting to call less often and not want to do anything with me anymore.  I feel lonely and abandened.  Will some one be my friend and does anyone else feel this way?  Please help
