I can relate to what you're going through since I am in the same boat. I think part of it is you're wondering what is going on with your husband's job. For me, some months, it's we're going to leave, then the other month is that we're staying here. So in the back of your mind it may be that it seems like a lot of wasted time and effort on your part to get a job you may have to leave several months later.
Are you worried about who is going to look after the kids or the cost of that? That is something to think about and may be impacting your motivation to job hunt as well.
