And your mother can't find a home, which means she is in a mess, unable to find a spiritual home and at a loss. She doesn't know where her heart belongs.
Her present state is that life has no goal and she is at a loss. What she needs to do is to set a goal in life. She can set a small goal first and achieve it bit by bit. In this process, she will find the goal of life and the destination in her heart:)
