The courts will hold you responsible for the terms of the lease you signed.
Terminate early and you may be sued.
That is why it is important when negotiating a contract that you ensure what you want is in writing. There are occassions where evidence of what someone said as part of the negotiations WILL be deemed as incorporated in the contract, but those are infrequent and nothing you posted indicates you'd be able to include what you were told as part of the agreement.
If you are desperate, see a local Landlord Tenant attorney and discuss options to see if you are willing to pay to buy your way out of the lease agreement.
