Of all the things I expected to finally push me to post here, I didn't expect it to be something like this.
So, I have a friend (Friend A) who I have known for years. We both have been diagnosed with social anxiety. Somehow she talked both herself and I into going to a party. Another friend (Friend B) is much ore extroverted and was happy that we were finally going to an event like that. However, she was disappointed that A and I spent much of the time we were there together and hiding away from the crowds. We told her multiple times that we had anxiety. The next day, she coincidentally finally started watching a show that A and I had wanted her to watch for a while. One of the main characters has anxiety. She started telling us about how much she related to him, but in a weird textbook kind of way (I don't know how to explain, but it didn't feel genuine, more like repeating something you'd heard). Then she began texting strangely. She was using a lot of emojis (I've texted her for years, never happened before) and when we asked about it she said that had OCD. She explained it strangely, but to me it sounded more like she was just a perfectionist. I asked if she had been diagnosed or if she took meds and she said she was diagnosed by her mom (a nurse) and it was minor enough that she didn't need meds.
At this A and I are rather confused and somewhat upset. It didn't really seem like OCD (I really don't mean to be insensitive), and her mom isn't a therapist or a psychiatrist, so I don't think she can diagnose mental disorders. As we see it there are three potential things happening:
1) B noticed that friend A and I are very close, and felt left out. She heard mentions of our anxiety and figured that the best way to get closer would be to have an anxiety disorder. Maybe she thought backing up the lie with her mom being a nurse would help? In this scenario I would like to get her to realize that anxiety is not some 'cool club' and that pretending to have it isn't cool.
2) B doesn't have OCD but legitimately thinks she does. She has mistaken a perfectionist nature for OCD and thinks her mom is qualified as a medical professional that can actually diagnose something like that. In this scenario I would want to have her realize that she doesn't have OCD because she thinks she has something that she doesn't and that doesn't seem good.
3) B legitimately has OCD and is very bad at explaining things. If this is the case I would want her to get properly diagnosed.
A and I really don't know what to do or how to approach this conversation. Neither of us are good at confrontation, and don't want to offend her. Any tips? (Also, I'm sorry for the length, I really didn't mean for this to get so long. I'm sorry)
