Just talk to her, Rayna. Tell her exactly how you're feeling and why you're feeling this way. Tell her you feel as though your bestfriend is no longer there for you as she once was. Explain things in a rational manner.

I'm going through something right now with my so called bestfriend that deals with jealousy and selfishness. It's hard to deal with it and I want to talk to her about it but she's completely shut me out and is ignoring me. So I can't talk to her. But your friend hasn't completely shut you out, it seems. So please try talking to her.
