To the OP -
Glad you started this thread because there has been a lot of good advice given on here. Hope you are taking notes.
One thing I heard today that I think many of us women in particular are prone to -
"Don't let your emotions dictate your decisions."
Often times one can't help but be emotional over big life changes such as the ones you are going through. But taking practical steps like those mentioned on here by others - list pros/cons, likes/dislikes, visit TV a few more times, rent first, etc - will build confidence in your decision making and hopefully diminish the emotional component somewhat.
Also, if you are able, take your time if you are feeling uncertain. Unless there is a pressing reason, why rush into something that you don't feel ready for?
Again, wishing you all the best.
