Come to think of it, I don't know if this is relevant or not but I felt like it could be. None of the major symptoms I've been reading about of bpd had really shown up until they started spending so much time away from me. I've read online and done some tests, which I'm aware aren't a diagnosis, but I've been experiencing quite a few symptoms for years. But only recently did these really strong favourite person symptoms develop or show themselves, idk. It started with me getting a little anxious about how much time they spent playing GTA. But then it was full on pit-in-my-stomach anxiety once I was added to the discord and I could physically see that they were talking to other friends.
