My best friend has been ill for a while and has been pretty sure she's had a serious illness but she'd been waiting for an appointment at the hospital for them to give her a official diagnosis. I'd rather not say what the illness is incase there's some way she could read this but she's been amazingly strong throughout this. All the time I've known her I've only ever heard her complain about this like 3 times.
She had an appointment this morning to find out if she's got what why thought she had. She said last week she was really nervous about this appointment but doesn't like talking about it because it makes it more scary. Obviously I wasn't going to make her talk when she didn't want to but I let her know I'm here for her if/when she wants to talk.
So I text her this morning to wish her luck with her appointment and I asked her to let me know what the doctor said. But because she's said before and last week that she doesn't want to talk about it I didn't ask how she was feeling about it because I knew she would rather try to be positive than think the worse. So I tried to stay up beat for her.
Then I got a text later on and she said she's been diagnosed with what they thought she has

. I asked her if she's feeling OK and she said she's just glad that now she knows for sure what's wrong with her and hopefully something can be done about it soon. She's got stuff on this afternoon so I haven't got to talk to her much yet but she's said she's feeling OK. I've told her again since this morning that I'm here if she wants to talk but argh what the hell do I say? I know she's quite happy for now to carry on as normal because she's not ill right now so she's trying to not let it bother her. But I'd hate to think she's keeping it all to herself and worrying about it without telling anyone. So do I try to get her to talk or just wait for her to come to me if she wants to?
Just feel like a bit of a bad friend if I don't try to talk about it. And feel silly talking about normal things when this is quite serious.
Argh what do I say/do?
