If you are a Christian and believe in Jesus you could tell her about him.

If not, let me tell you that Jesus changed my life completely. There is joy, piece and meaning in life that I did not have before.
Hope this verse encourages you:

Deuteronomy 31:8
The LORD himself goes before you and will be with you; he will never leave you nor forsake you. Do not be afraid; do not be discouraged.

God bless
