Right Move?

I feel a bit like this magpie today, wondering if I'm making the right move. Tomorrow is 'putting in an offer' day and the stress is getting to me. If I get this house, I'm never moving again. I will retire in it. And if I don't get it, I will be thankful that I have a good job, a roof over my head, food on the table, and family to see me through my mini meltdowns :-)
