It sounds harsh, and I don’t mean it like that, I’m not sure how to get it across completely kindly.
Don’t tell everyone about how hard it is to be away from house/kids/family unless you’re absolutely sure they can relate.
Depending on what sort of job she has, she may feel lost at first, chances are she’ll do fine and the people around her won’t ever think she’s lost. Unless she tells them how out of place she feels, how much she misses the way things were, and how unsure she is.
In the office: Show everyone what you can do, then get to know them, then tell them about yourself. For better or worse, work is about production.
Outside the office, in our day to day lives: It’s exactly the opposite, you tell people about yourself, get to know them, and then they learn what you can do. It’s about who you are.
And just like anyone else, after you get your feet wet and feel good about it, don’t settle, find something you love and go for it. If it’s not that first job, just get through it for a while until something great comes along.
