When someone doesn't put kisses on an email...

[HelloKitty76]

When it's something they normally do...

Is it BU to wonder whether you've perhaps upset them or their feelings towards you have changed for the worse?

It also depends what you emailed first, if you did. Sorry, just trying to understand content.

I don't want to out myself but I emailed her because I was having a bit of a freak out about something, so was hoping she'd reply with something supportive, especially as I'm just coming up to a big event. But she didn't!

The whole tone of the message sounded a bit like she was shouting at me to be honest

I think you look for problems where none may exist and read negativity into anything that's written.
So what if she didn't put a kiss? Why assume it's your fault?
If the tone of her email was like she was shouting at you, then you should be thinking, 'what the fuck has rattled her!' not 'Oh dear, what have I done?'
If you've done nothing wrong, stop worrying about what she may or may not mean!
