Riddled With Anxiety ( What would you do Part 2 from yesterday)

We have been gone since 12:30 today.  I have so many different things that I need to do.  I feel anxious for that reason, but also because I am hoping the phone doesn't ring.  I need to leave the ringer on because my husband will call in a bit.

Yesterday, I posted about not wanting to chat on the phone.  This person tried to call twice in a matter of hours.  She left a message the second time, but my husband listened to it for me.  It was just chatter on the voice mail. So, this is three calls and two messages in less than a week.  I am busy every day this week.  When I am home, I don't want to chat for an hour on the phone. I don't mind short conversations, but she always wants to talk longer.  Its usually about the same things just a different day. It might not be, but I am not up to finding out.  I don't have the patience for it, but I don't want to be unkind.  I don't understand why she can't email me because I don't have a problem answering emails.

What do would you do?  I mean about more than one call and message.  Do you email the person?  Do you ignore the messages? I am at a loss for what to do. 

I think it's because I had a few unpleasant experiences with this person that is adding to my anxiety.  I don't want a backlash from her. I just don't feel like talking.
