Laurie, sorry to hear about your brother, and wishing him peace in his struggles. Here's my read on neglected gardens - whatever you CAN get done is positive and will reward you, sometimes unexpectedly (e.g., a full flush of bloom sprouting through the weeds). Rather than being overwhelmed by what you can't or haven't accomplished, celebrate the tenacity of plants that succeed despite all odds. Godspeed to you and your family.
