I'm not going to talk to my best friend, as they kind of ditched me.
What did they do, if you do not mind me asking?
I spoke about moving and she started to ignore me.
Moving, even the mention of it, is a major deal for all and your friend is probably just trying to process the possible loss of you. Have a talk and relate that your friendship won't change, just geography.
We haven't spoken in 3 days. They should feel bad for making me worry. My feelings are more important anyway.
Thinking that your feelings are more important is a very selfish thing. You and your friends' feelings are equally important so again, reach out to them to talk about the move. They are likely upset and inadvertently making you upset in the process.
