Moving from Family/Job Change

My husband could get a really good job, but it would be about 5 hours away from family. He’d be fine with moving, but I’m hesitant. I have always been close with my family.

We have 2 kids, and I am pregnant with the 3rd. Part of me wants to try something new (I struggle with anxiety/depression and am currently VERY unhappy with my job), but the other part of me is scared to move where I know no one and leave my family.

We currently only live a mile from my family and 40 minutes from my husband’s family.

Have any of you done this? Thoughts, experiences?
