So my friend N and I planned to go to the carnival together like a month prior to day-of and since our other friend A had been feeling down, we invited her. 
She told us she didn't want to go and that she felt sick anyway so we were like oh alright and we went without her. 
Then all of a sudden once the time we met up/ were to meet up came around, A started texting us about how she really wanted to go and that her parents are apparently abusive because they didn't let her go ??? even though she'd decided not to go. 
When I was at the carnival, I had little to no reception. Enough to receive messages but not enough to send messages. None of my texts would send, so I stopped looking at my phone. A kept spamming me insults about my appearance and weight, calling me a terrible person and friend, "a greedy inconsiderate elephant", etc. for going without her.
Once I was home, I replied to her and explained why I didn't text back (no reception) and she said "bs lmao" then went on for 3 hours insulting me with comments not relating or only loosely relating to the situation.
