Firstly, let her realize that the life she’s living, isn’t hers but God’s.
Secondly, let her love herself for who she is, and make sure to do only those things she enjoys doing….. Advice her to free herself also from every past event that doesn’t add to her value at the moment……. She shouldn’t be in isolation for a long time,..let her mingle with others and try as well to solve people’s problems(put smile on others) as this also gives inner peace and satisfaction!
Above all, let her have a moment with God in her private time once in a while, and the Lord will show her great and mighty things that she knows not.
Sending Love to her from my end
