Friendship ended after fight
I'm really anxious about a friendship breaking down. I was visiting a friend in Dundee and passed throigh Edinburgh where another friend lives. I went through to get to Edinbrugh on the train to get to my destination, and on the way home I spent a few hours in Edinburgh and grabbed lunch with the friend i was visiting, this was on a whim.
These two friends fell out a long time ago and don't talk, so I'm always awkwardly stuck in thr middle.
I was only in Edinburgh for a few hours and posted about being with my other friend on Instagram, showing that i was in Scotland in a different city 1.5 hours away. On the train home I got a long text saying they were really hurt that I'd been so inconsiderate and selfish by not telling them I'd be there and trying to meet up. I also had another friend message to tell me I'd done the wrong thing and really hurt our mutual friend.
We had an argument about it because I really didn't think what they were asking was fair, and they were sending me paragraphs about how hurtful and unempathetic I'd been for posting on Instagram where they could see without telling them I'd be passing through.
The friendship is over and I feel really worried that I did the wrong thing and should have just apologised, and that I was being unempathetic and mean. I just felt like the reaction was so intense and cruel, telling me I'd done something wrong and been inconsiderate and sending me paragraphs about how much I'd hurt her feelings by being so selfish. I dont know anyone else who would react like this! I have OCD and severe anxiety and stuff like this really throws me
