Well, a new friend came along that isn't going away anytime soon because of ties to my friend group. We immediately clicked extremely well and our relationship has been nearly infantalized amongst the group. She is still in her late teens and I'm in my mid 20s. They say things like she "looks up to me so much" and "talks about me all the time" and is very "excited about me". Unfortunately the rest of the group is very unfamiliar with any mental illness beyond depression or anxiety. I personally have bipolar disorder so I don't particularly have this luxury, and due to a few reasons have a lot of prior knowledge about borderline. 

I've noticed clear symptoms manifesting in our friendship. Pedestaling, emulation, and extreme feelings, mostly. The emulation is super obvious. She has decided she's going to change her entire personal aesthetic to mimic mine and she thinks it's the coolest thing she's ever heard. 

To be completely honest, this type of behavior doesn't bother me personally. I'm not really concerned about how it's going to affect me, as I've had a lot of experience with people who have personality and mood disorders in my personal life and just kinda take it without issue so long as they're not my SO. 

I'm mostly concerned about how I'd potententially enable her. I don't want to make things worse for her or encourage her, and I think my lack of reaction to her extremes could be great, but also potentially bad? Basically, I dont know how to have a healthy relationship with someone who is borderline. I have one other friend who is borderline but doesn't project almost any of her symptoms on me, so I have no experience here. 

I know I've just driven the anxiety rate in this sub up with yall reading into this being afraid its you. But I'm pretty sure she doesn't use reddit :) throwaway just in case though. 

Any help about healthy friendships with a borderline bud while being on the pedastaling end would be much appreciated. Advice, resources, etc. Thanks guys!
