Based on the limited information you provided, it looks like you're on the hook for the one year lease. "Cold feet" and change of heart are not sufficient reasons to break a lease. You can try to find someone else to take over the lease to mitigate the landlord's damages.
Talk to the land lord and see if he is wiling to let you out if you can get someone else in. Otherwise, it may be difficult to avoid staying out the one year contract.
You are probably on the hook. It usually takes something more severe than cold feet to get a tenant out of a lease. If you have not moved in yet, call the landlord and see if he will let you out. He might be willing. Check the guide at the link below which will give you a description of some of the valid reasons for ending a lease early. Maybe one of those exists and you just don't know it.
I agree with the other attorneys, you don't have a sufficient basis to break the lease, see if you can sublet if allowed or ask the landlord if you can agree on vacating the property and getting out of the lease?
