Hey DarkRider, sorry to hear about your situation. In the US It's a universal rule as far as I know, that land lords must give a 30 day notice for eviction. Also if you are on a lease, the eviction notice time frame is usually longer than 30 days (depending on state and duration remaining on the lease). So you shouldn't simply fold up shop, 3 days notice is BS, and that landlord should be ashamed of himself.
Incidentally, unless you have eviction paperwork issued by the landlord 30 days ago, you don't have to go anywhere. He can't force you out, the cops won't remove you without a court order which would never be issued until actual eviction paperwork is ordered, so DO NOT LEAVE. You have rights and even without the means to getting a lawyer, the burden of the situation is entire on your D-bag of a landlord
EDIT: I looked it up and Illinois requires 30 days notice for eviction unless you have failed to keep up on the rent. If you are late, he can give you a 5 day written warning to pay or evict, and then if you fail that 5 day notice, he then must give you a 30 day eviction notice IN WRITING. The pay warning must be 10 days if you have a lease which is greater than 1 month. Burden of proof in any case against you to evict is on your land lord. You DO NOT have to leave. He also cannot force you out by shutting off utilities and the like.
