The service of giving attention to another self

[I am Shayne]

I have totally felt the same anxiety. I am a listener, and I've experienced that talkers love to speak their thoughts in the presence of a listener, and they 'generally' aren't open to other perspectives or solutions. Ive found that some people just want to use your open ears, and they use their own words to process their catalyst.
I think the fact that you are listening is good service to them, and I think that believing that you are being of service can alleviate the anxiety. It has for me.
