Call me if you need anything.

How can I help?

I'm sorry to hear that.

Is there anything I can do?

Let me know what I can do.

My condolences.

Oh, I'm so sorry.

That must have been awful.

That sucks.

That's a nuisance.

That's a shame.

That's awful.

That's terrible.

That's too bad.

What a bummer.

What a pity.

What can we do to help?
