That must be really hard for you.
Wow. You don’t deserve that.
How do you feel about it now?
Ugh. That sounds awful.
You’re handling this better than I would.
How do you even respond to that?
Tell me about it.
What can I do to help?
You’ve got this, but I’m here.

Edit: I wrote the above to illustrate how many options there are in the parlance of active listening. The formula is simple: imagine how they feel and join their side or, if you can’t yet imagine, ask questions until you can. That’s it.
