Apt. MISERY — need help. Landlord promised a quiet environment verbally but promise was not kept. It has been?

This place is awful– police have been out here multiple times for noise complaints but its been going on for 2 months now and apparently they never cite them because “its a university town and kids party”.
I have lost sleep, been placed on meds for stress and my schooling has been ruined – focus concentration so bad I had to drop from my own classes. I cant afford a good attorney and the landlord wont let me out unless I sublease which means I am responsible if someone damages the apartment. I’ve contacted everyone, including the press and the a police captain and a police colonel. Anyone have any ideas as to why the landlord wont admit his lies and let me out? Especially as its been making me ill?
