I (18F) have a friend, "C," (19F) who I've known for about 3 years now. We're decently close and she's a very sweet and thoughtful. However, C is a chronic overthinker and has been that way since we met. It started off as philosophical/ethical questions like whether it's possible to be racist towards our own race, what's after death, etc. But this summer, it's worsened to the point where it's making me uncomfortable and frustrated. The last time C and I hung out (early summer), she looked very distressed. When I asked her what was wrong, she started saying how she thinks wrongdoings define you as a person and was basically stuck in the past about her faults. I reassured her that we all make mistakes, but it's human and the important thing is that we grow (basically that mistakes may be 20% of us, for example, but there is still the 80% that's more important in defining who we are). C proceeded to start comparing us, saying that she's a worse person than me, that her mistakes were bigger than mine. Some of the mistakes she listed were being mean to her mom and glaring at a girl out of jealousy when she was little. When she started getting loud and we got some stares, I forced us to talk about a different topic. Over the past couple days, she texted me panicking and asking to call. When I picked up, C was in a fit because a guy that she was practicing a language with invited her to meet up (she initiated the request to practice the foreign language). I first asked her if she wanted to, and she said no, so I told her to politely decline. The whole time was a struggle because I'd suggest one thing, and she would go round and round in circles overthinking about whether it was weird to say it that way. Earlier, C called again panicking because the guy suggested that they call. Again, I asked her if she wanted to, and when she said no, I told her to let the guy know she'd be more comfortable texting. C then insisted that it was awkward and embarrassing. We went in circles, basically going like this: C: But it's so awkward and embarrassing right? Me: I personally don't think so but it's your opinion C: But I don't want to think it's awkward Me: Then don't think it's awkward...I can't change what you think C: Okay but even if I don't think it's awkward, it still seems awkward right? Me: Again Idts but can't change what you think. I'm just giving you suggestions. C: But if you were me what would you do? The whole time I was just at my wits' end because I wanted to empathize, but no matter what I said she'd just find a way to direct it back to what she thought. I think her anxiety is affecting her and I know that it's something she can't control. I'm not sure what to do since I value our friendship and this will probably be the last time we meet before I go off to college. However, I'm scared that this will be like last time, or even worse because if she brings this topic up again I might just explode. WIBTA if I canceled our hangout?
