Well I think any big changes in life bring an element of fear with them.
When I left my husband I was scared.... I was going to be a single mom with a 3 and 5 year old. I did it anyway because it was the right decision. I got through it.
When I left my secure but crappy job I was scared.... I didn't know if it was going to work out. It was the right decision and I got though it.
I think it's natural to fear big changes, sometimes fear can be the catalyst that motivates change.
I'm addressing my fears by talking about them right now.
