<human>: Hey guys, I co-leased a house earlier this year with some roommates.  The lease was for a year and I ended up moving out of the house in May because I couldnt afford it (i have a text from them acknowledging that I was leaving).  My roommates said that if I would stay on the lease so that they could avoid the hassel of dealing with our crazed landlord they would return my security deposit out of their pockets, since usually you just have to wait for the lease to expire.  Obviously this is a bad idea and I knew this at the time, but I was in desprate need of my security deposit and semi-trusted them not to fuck everything up... Now it turns out that after I moved out they tried growing pot, the landlord found out, and they decided to leave.  Their "modifications" made to one of the rooms for growing caused a bunch of damages to the house.  They didn't give me my deposit back afterall (awesome) and now I have a landlord telling me that the deposit is being applied to one of the months that wasnt paid for and I also owe $4,000 for various damages and rent for the time that the house was not occupied.  What should I do!?  I know what I should not HAVE done, but what should I do now??  Thanks!

Summarize the given text in a few sentences.
<bot>: rented house; moved out; didnt talk to landlord about moving; roommates damaged house growing pot and didnt pay rent; I am now liable...
