I don't think it's right to confess, not so soon anyway.
As what the other forumites have said, be there for her.
Go through with her this bad patch of her life, and she may treat
you as someone closer.
There comes a time when asking her out for movies 1-on-1 and dinner
is so normal and so enjoyable, then when you hold her hand, it may
be just so natural...
Of course, it may not happen that way, but still, i think that's
best.
Good luck.~
