You've had some good advice here ... so, at present, there isn't really anything I can add to what's already been said. However, to the friendly, online filipino/uk community. I hope your half-sister will soon overcome her feelings of isolation. ... perhaps she might even consider joining you as a member of this site. In any event, we're here to help ... and if you feel we can be of further assistance, then please don't hesitate to contact us.
