i have discovered something greatly heartbreaking that has shattered my ability to trust, and i am not sure i will ever be whole again

one of my rats, bear, has secretly been pooping in hidden, difficult to access places in my room. i had long been confident that she did not do such a thing, but she is. i thought i had escaped toxic people in my life but the most toxic person was right in front of me this whole time. she still hasnt apologized or made any indication that she intends to change her behavior, and i dont think she ever will. im so tired of all the drama and so tired of fake people
