i put in an application for an apartment, was this a lease i signed, im scared?

my grandparents are moving to michigan with the rest of my family and i am staying in texas so i decided to get an apartment. i fill out an app. and sign a few places, isnt an application usually a page long? they gave it to me in a packet stapled together and told me to fill it out and bring it back, my roomy and i hadnt fully decided on it.. shortly after, i checked apartmentratings.com (which by the way i should have found before hand, has hillarious stories at least to those who dont have to live there) i guess i dont have to say that this apt. doesnt have the rep of the homliest place in sherman. . in fact of the 9 residents that lived there and rated it, 1 claims that it is inhabitable for humans.. things leak no one would fix em, outdated stuff, bad service, electricity bill skyrocketted cause of lack of maintennce, drugs.. well i called today to see if the ap. went through and they said our apartment would be ready tomorrow. im scared i may have signed the lease. i feel stupid
