Kudos on the self discipline!
Esp on not taking it personally or getting defensive (adding to your own load) or let your emotions take the spotlight.
When she came to you for help, you were able to keep the spotlight focus on her and her problems and what she might need at this time (ex: an ear, comfort, support.) And in providing the need (comfort, support) you were able to help lessen and TAKE AWAY from her load rather than ADD to her load.
Sounds like both of you came out of it in a good way.
