Well... I agree with MIII... see how it goes... you never know it might turn out ok. I know exactly how you feel I did the same exact thing at your age... I moved back down to live with my mom. For me though I didn't have a nice job (I did concrete capping) and missed most of my friends up here, plus I didn't even have a drivers license. I only lasted about 8 months. I say if in 6 months you still don't like it you should move back up here. At least miss the winter up here
Then again I don't know the details of your circumstance.
Good luck though.
