What to do...

How do you ask/tell something you know will be upsetting? It's important that I ask/tell or find a way around it but I don't like being sneaky about this. I'm trying to build up my courage and talk about it anyway, even though I know it will be bad and she will not be open and will not be understanding at all. She will be disappointed but I think I could handle it because with they way things are going, she's going to be disappointed in my a lot and I really don't care anymore, she's so unreasonable... I just don't know. I guess I will have to talk to Harry and see what he says... We have a lot to talk about....
