Some people are just toxic, thrive on confrontation and controversy and arguing. I'm not at all like that, and I would compromise with the neighbor, seek out an agreement to get along if it were possible. With this person, it is NOT possible! I've lived here for about 6 years, and every interaction with this woman has been toxic, with her spewing venom! Within the past year, I started spewing back, defending myself, but I don't like to be in such a venomous relationship. Recently, I've even thought it might be worthwhile to my mental health to sell my house and move, but I have too much invested in this property to recover it financially in this housing market. Sadly, I've allowed this situation to infect my own well-being for a couple of weeks now, feeling anxiety, even panic attacks. I feel certain she intends to poison my cat, so I've kept him inside unhappily during the day while I'm at work. Recently she stood outside saying she was going to kill him. He is very unhappy and I do let him out for a few hours when I return home. (Back when we were on speaking terms, she even told me at one point that she was thinking of doing something to him, and she has already poisoned my two other cats.) I call for "Kitty" anxiously at bedtime and so far he has returned to sleep with me, but I'm concerned anytime he goes out.
So, at this point, I'm gradually getting beyond the anxiety. Realizing I have allowed this toxic person to affect me adversely.
