Hi!
Try to look for Pinoys in your area and make friends with them...it will help her alot coping with homesickness...try any Catholic/Christian churches. I met my 1st pinoy friends in a church then from then on I met the rest in pinoy parties. Staying at home will not help...try to go out as much as possible or just keep her busy with other things. If she can work, part time will be fine she will meet more friends.
