Sorry your feeling bad. Not a diabetic here, however everyone else in my family is, so only a matter of time for me.
If I am reading the other threads correctly, you are getting what you asked for. Sometimes the last thing a person needs is exactly what they asked for. This is evidently one of those times.
Couple of easy choices, stay the course you will get used to the stress, could take a while though. or--- Give up through the towel in, get rid of the chickens, pay your fine and walk away.
However, I do not think that will relieve the stress, because the lady next door will then find the next thing to push your button. And I garauntee if not the chickens it would be something else. So it is a matter of choosing when to fight your battle, now, over the chickens or later over the unknown.
Can I ask in a civil manner, just how old is the lady next door? 60? 70? 80? You know, no one lives forever. My idea of old has changed and continues to change as I get OLDER.
