I think I just need people's thoughts on this because it's been driving me mad for a while now and I'm at a loss of what to do.
Me and my best friend (both 24f) have been close for 6 years now. I'm disabled so admittedly I have more free time on my hands, and she has just started university after living abroad for a little while. When she started university she got into a group of friends and she seemed to become totally consumed with them. She would go out drinking, smoking, taking drugs, and then come back the next day to me and tell me she didn't want that life and she didn't know why she was doing it.
We were the type to talk at least once daily, even just a quick hello, and catch up when we could, but she just hearts messages and doesn't reply for sometimes days and weeks at a time. I've tried to talk to her about it all, and about how pushed out I've felt (in nicer terms) and she at first said she would be more present, but it seemed to only snowball. She got into a relationship with a known abuser, but has told everyone she doesn't believe in what people have said about him. Then she came back to our hometown for a few weeks, and none of the friends she had made got in touch with her. She came crying to me about it and I supported her. She went back, and I didn't hear from her for weeks.
I got a cancer diagnosis a few weeks back, and I told her this. It's completely shattered my mental health. She just said that it was sad and went back to ignoring me. I asked if I could talk to her and she made an excuse.
I'm not someone with a huge friend group, and with my recent health I've had people distance themselves massively and it feels so lonely. I miss her but I don't recognise her anymore. She's told me that she isn't helpful, isn't complex enough to help me anymore, that she's changed. I asked her if it would be best I leave and she begged me to stay. I don't know what she wants and it's too painful for me to demote her to a lower 'level' but she won't entertain a conversation with me anymore
She rarely asks how I am, and isn't interested in any conversation that isn't about herself and her partner, or drinking. To a point where she has forgotten things about me that are really easy to remember. Even my birthday she forgot last year
