I agree. You may need to speak with an attorney about this, but it depends on how your lease reads. But one question, I have never done a lease that the broker does not ask what your business is. Did you tell the broker or lessor? Only the written really makes a difference, but if you told them what you did and they had knoweldge of that, an attorney may be able to use that for leverage to get you out of the lease. Also, negotitation with the lessor may be possible. Read your lease and talk to the lessor. Maybe you can work it out. If not, consult an attorney.
