I think it is really kind and giving of you to want to help your friend with this, and I agree with all the above sentiments. Doing something - anything - will tend to pull you out of yourself and help your energy start to flow.

But another thing that you can do for your friend, and which I've always found remarkably healing if people will do it, is just listen. Let them talk about what's going on with them, and listen, without offering advice, without offering judgement unless asked. It sometimes helps a person just to get this stuff out in the air.
