I say - If that's what you need to do to jump-start your life then you should do it! I moved back in with my parents for 3 years after being on my own for 2 years. I hated it at first, but then we came to an understanding - I pay them a small amount of rent each month and help around the house and they put the money I give them for rent into an account that they give me when I move out. Everything worked out great!
Do whatever will help you be happy.
