Made a huge life change and starting to regret it...?

For the last several years we've lived in New England. It's where my babies were born, its where majority of my family lives and where we thought we would be building our lives then everything went to shit and financially we couldn't afford it anymore, the prices of everything more than tripled so no matter how many raises, we were barely getting by. We made the tough decision to leave and move to our home state of NC to live with my dad for a bit while we got situated then rebuild our life. That was September and here we are nearly April, still living with my dad and im really fucking depressed. My husband had to take a pay cut down here so what we could have easily afforded there is too high right now. I miss our old house, i miss living with just my husband and kids, i miss my niece and sister in law, i miss having family there to watch the kids if i needed a break for an hour or two. Im so lonely and i feel like i failed my kids by taking them away from everything they knew, i wish that we never left because now, we can't go back. Im sure my husband could get his old job back but theres absolutely zero rentals and even if we could buy, theres no houses. Anyways...thats my cant stop crying rant...
