potty training relapse after two years?!

Hi everyone :) I am new to this site. My two year old lab mix mocha and I just moved to buffalo from florida. We don't have a fenced in back yard like back at home but the first couple weeks she went potty on the leash just fine. Now for the past three weeks she has been pooping and peeing in our guest bedroom. Mocha is not crate trained she has severe separation anxiety and rips all her toenails off. I don't know why she all of a sudden started going in the guest bedroom. I welcome any suggestions you guys have for me. We are looking for a professional trainer but I just got a new job and I need to wait a little before I can afford a trainer.
