Just let them know you are there. It is something they have to pass through, you cannot change it for them. But it will help knowing someone cares and is there.
Forget the words "I know how you feel." It's unlikely. You okay?
By telling them I love them, I am here for them and asking what they need.
Yeah, either that or I'd whap upside their head and tell them to buck up and snap out of it... ;)
I would realize my friend was hurting and needed to be held or just to know I was there; advice isn't something all hurting people want or even need; just listening, just being there, can be helpful and reassuring.
Be present for them and listen.
a good friendship!!!
Make him/her laugh.
By taking him/her to her fav bar
by fu-ckin-g her hard and fast.
