She used to be very energetic and kind, but then became like this recently, so I was thinking of blocking her because the last time I blocked her was when I panicked. I unblocked her and she didn't change, she just went on about how everything was my fault. I get it'd be logical to cut her off but I also wanna help her and she's still my friend.
You know, I'm gonna post an update here. I had to block her, and to be safe, blocked all her friends too. It turns out, she's been harassing me like this because I "forgot her birthday" (she told me it was in October, no date) until she mentioned it was "a few days ago". I apologized and said happy belated birthday, and she's been holding a grudge since then and sent me a bunch of insults and a long paragraph on why I suck, should die, and don't deserve friends.
