Sorry I'm just reading this now. When I first heard of all the devastation in the Philippines I thought of SDA lady & I wondered how it was affecting you. This is not an easy situation. But it is a good time for you to reach out to her as a friend but to maintain the boundaries already set. She does have other support there & if you went in person - you could very easily get sucked back into the drama. (I don't mean that to sound harsh).
You let her know that you care. And you do care. Leave it be and pray. See how she handles it by contacting you or not.
The world cares. You could make a donation if that might make you feel better.
