My advice in your situation would be: don't rush it. There's plenty of time to make these decisions when you are not shell-shocked. The important thing is the insight, the change of perspective. The decisions will follow naturally, but no need to make them while you're still dazed and confused.
A week or a month won't make that much difference to your decision - but they will mean that when you look back at it a year later, it won't be with the feeling that perhaps you rushed the decision.
