Perhaps if you talk to your friend about what she can do, how she has coped with this ability, how it made her feel at start and how she feels now etc.
If you talk with her about everything she has been through then you might be able to wrap your head around abit more. Atleast you'll know your friend better and Im sure she will feel good at been able to talk about that side of things with somebody. Then if you dont want to be told things or know stuff, you can let her know.
Im very curious as to what she has told you now
