I hope the new job gives you a new perspective. 3 of my kids have recently gone through the new job fears (please don't think that I'm trivializing your feelings). It's overwhelming starting a job where you don't know the ropes. The information they give you just makes your head want to explode.....But remember, you're not expected to instantaneously memorize it on day one. It will come to you bit by bit.
People will not dislike you.....if that was the case, then you wouldn't have gotten the job.
This is a door opening for you, not a field of barbed wire and land mines

Hugs
Keep us posted on how it goes.....I want to know..
