I would take as much time as you need to reevaluate what you want. Take alot of time doing that.
These are pretty much my thoughts. I don't think you need to wait a hard and fast year. But do take as much time as you need. Let the initial shock of reality wear off so you will know and will be confident you are making a sound decision. If your decision is give it a year at that point, so be it. If your decision is to move on at that point, then go that route.
I think you're in one day at a time territory at this point.
