You can always start slow by working part time if you can. It will help you feel out staying at home and ease you into it. It will give you a chance to overcome some of those fears while allowing yourself too continue working. In the future, if you had to get a job again after being a stay at home mom, there are always other options. They may not be in your field, but there are things, even like running a daycare out of your home. My neighbor does that and it addresses most the concerns you brought up. She had no prior experience but she loves it.
