Friends may think they know what you need to feel better — get outside and do yard work, go to the movies, get a tattoo (my sister’s idea), go kayaking, get drunk so that you can forget grief for a few hours.
They might have religious books they think you should read, or a Russian novel that you can lose yourself in for a week. In happier times, they might be right.
If friends come in thinking that they know what you need before hearing you talk, politely ask them to leave. Listening to them might set your recovery back.
