I was stuck in a weird place too. I was slowly shifting out of the joyous party lifestyle I'd enjoyed for em, let's say a couple of years. But also, totally wasn't ready to batten down the hatches, embark on a mortgage, husband and kids. In my eyes, this year was going to give me time to get over the hump.
I wanted to be sound and give enough time for replacements to be gotten, handovers to happen etc so gave three months notice. My tip for the top here is to give as little notice as is possible. You try really, really hard to stay focused but the whole time you have a song running through your head:
In my instance, I was lucky enough to be able to enjoy the luxury of a sabbatical. This is something that doesn't happen very often from what I can gather from various peoples reactions when I told them I was taking a sabbatical. I did however have to contend with the possibility of just giving up my job and at thirty, this is something that you don't decide on easily.
However, the way I finally got to the point of making the decision was, corny as it sounds, you do only live once. You have one chance at this and although I loved my job, the six years could blend into one. This one year would stick out forever. Nike really did hit the nail on the head when they said, Just Do It!
