Renee I totally understand what you have been through, the frustration can be overwhelming and at times seems extremely personal. Only you know what’s right for you.
I believe you said that you tried the battery disconnect, did you leave the power off for a couple of minutes?
If not you can give that a try. If it still continues and it’s all of the lights in a zone, it sounds like a control board that is going out. One more thought, can you try and dim or un-dim the ceiling lights? I don’t believe it’s a ground issue if only one circuit is effected
