<human>: It seems my girlfriend is getting annoyed with my reaction to negative things that happen in her life. Being a LDR doesn't make it easier. 

They're not major issues, just daily annoyances in her life for the most part, but they seem to come up a lot more than than used to.

When one is brought up, I feel for her, tell her I'm sorry and ask her a few questions on it and honestly do listen. Good so far.

But... beyond that, I'm simply out of conversation. Her being sad makes me sad. 

Then, she gets annoyed because it gets quiet or I try to change the subject. (We use Google Hangouts being about a 6 hour drive apart in Washington)

Can you condense the text into three sentences or less?
<bot>: I empathize with a negative event with the GF, but it bums me out and I quickly run out of questions or talking points which annoys her further. No idea where to go from there.
