<human>: Can you succinctly summarize the text in 1-3 sentences?

So I made a friend online, just kinda happened.  Been talking for nearly a year, all playful banter and stuff.  She sends a message one day talking about how she was diagnosed with mental issues.  (She mentioned earlier about depression and stuff, so a diagnosis wasn't all *that* surprising) From her tone I thought she didn't want to talk about it.  I try to lighten her up by making an relevant in joke about it.  Apparently she didn't think it was funny and said I was not caring or trivializing her problems.  I said sorry, but she stayed mad and didn't talk to me for a few days.  She resurfaces and we talk for literally one minute and she says, "I'm gonna live in Ireland once I get my own place"  I make a joke about having to be an alcoholic to get residence.  
She didn't think it was funny and replied with a stunted message. 

Thing was I always made these types of jokes for like, the entirety of out friendship and she always seemed cool with it to me.
So I tried again on the off chance she was just being affectionately crude.  Confirmed, she did not find that funny either.  Now she is even *more* angry at me than she already was.  

She said she was *never* cool with it and it always annoyed her.
To me this was never prevalent because all she ever said when I made a joke deprecating her country was "Rude" or something.  I just interpreted this as like a humorous response.  

Anyway.
<bot>: I'm not funny, I'm rude, and I don't know how to deal with people telling me their problems.
