Liz, ((((hugs)))) and all this spinning is normal. Change can be scary, it can also be liberating, educational and a great boost to your self esteem when you look back and say "Wow, I did that!"
Don't know if you've been following my posts but I just made a leap of faith. I quit my job in New Jersey so I could move to Memphis and be closer to my family and grandkids.
I am now living with my daughter and son-in-law and have found a new job, which I love. In a couple of months I'll start looking for an apartment. It was scary making the move with no prospects or anything like that. It was also possibly the best thing I have ever done.
So, instead of looking at what might go wrong or even what might go right just try to take it one day at a time. I know, easier said than done but it does help.
Your friend,
Mike
