After signing a lease for an apartment, do I have a time frame where I can legally opt out before being commited to it?

Question Details:

I signed a lease on Monday afternoon and was told yesterday that I could not get out of it, even though it was less than 24 hrs later. I've been told the community is not safe and I want out of my lease. I was also told that I forfeited my deposit upon signing the lease. Important Notice
