You can either avoid contact with the elders, remain silent or tell them the truth:
You are having a very hard time just now with personal stuff, and you are praying and trying to work it out.
They are very kind to take time from their very busy schedule to visit you and you really, really appreciate their concern. However there is nothing they can do at the moment. You will be in touch when you feel they can help...................and "thank you again for your loving concern".
No need to lie.
Just tell them what you feel they should know.
Now where have I heard that before.
