I don't understand abandoning all of your things when so much of it will not be affected. I also don't understand abandoning clothing when it can be cleaned properly to remove bedbugs and their eggs. Just because you are upset doesn't mean you should loose all sense of reasoning. There are right ways and wrong ways to go about this problem. You are going the wrong way about it. Go through the right channels to break your lease, if it can be broken. If the professional won't give you something written showing how long he believes the infestation has been in the apartment, find out of another one will. If they say longer than you lived there you have proof that the landlord bears responsibility. Sure hope you bagged and tied up those clothes and kept them outside at your parents house before you washed each bag one by one.
