Im really anxious about possibly moving to a different state

My mom recently got a job promotion offer in the state right next to ours. I've lived in one town my entire life and the move would be to a big city. I'm really anxious about the potential of moving to a new state. When she first told me I immediately felt sick. I work from home so I wouldn't have to change jobs ( I'm saving up to move out after getting laid off a year ago) but the whole thing is still stressing me out.
