<human>: So my girlfriend of a year(today is our 1 year anniversary) has these freak outs, where she will freak out at me and others every month on our anniversary.  Tonight we were watching TV and cuddling after a gift exchange, and she just freaked out and left.

I don't know why she does this, and I in turn freak out because it feels like she just sees it as another month wasted with me.  And I've talked to her about it, and she assures me this isn't the case but that she doesn't know why it happens.

Has anyone else had this problem?

Can you condense the text into three sentences or less?
<bot>: My girlfriend of a year freaks out every month on our anniversary and I want advice and/or an idea to why she does this.
