Reposting here, hoping for more responses...
DD (15) is having best friend troubles at the moment. She used to go to primary school with this girl, but now they mostly talk on social media and see each other every few months. Both considered the other their best friend.
A month ago DD and her friend were talking, but she never replied to DD's last message (although it was 'seen').
Now, DD has OCD, and while her friend may not know this, at the very least she knows that DD has mental health issues.
Then, another week later, DD said her friend posted something on facebook indirectly about her, saying something along the lines of 'it's so annoying when people do XXX, I hate it so much. Like wth is wrong with you?' - DD says while she is not 100% sure it is about her, she definitely does the action that her friend mentioned, and she was extremely hurt that her friend posted this. She has never felt judged for her behaviors before by any of her friends, I think she is very shocked and hurt that her best friend would be the first/only person to do this.
Now DD's friend has recently made an instagram post thanking people for 1k, and she tagged all of her friends (including people less close to her than DD was/is), but DD was not included on this. DD feels very hurt by this, because although she was very upset by her friend, she still considered her a friend.
Should DD reach out to her friend again and say something? Or should she just let this one go? I'm not really sure how to advise her, perhaps it has all been a misunderstanding?
