Hi Jemma,
Actions speak louder than words, and the fact that your here
means your freind has someone special to support her.
All you can do is let her know you are there for her, and wait
until she directly or indirectly lets you know how you can help.
If she is shy, pushing the point too hard may well end in isolation,
so easy does it...
When there is something more specific to deal with, post your
questions here, and I'm sure help will be at hand.
My best wishes to you both in these difficult times...
