I'm new here and am seeking hope

Good Evening,

My wife was diagnosed with ADHD in the last year and a half. Due to numerous other ailments that are finally diagnosed and being treated, she is not currently on ADHD meds. She has taken antidepressants in the past (that I am adamantly against due to side effects).

I have joined a few ADHD spouse groups and have found them to be pure depression! I can identify with other's experiences, but everything looks dire for everyone with divorce or extreme submission to the disorder (giving up all my needs) being the final options.

Every podcast I listen to or article I read says to avoid the parent-child dynamic and other things to avoid. That's great, but what DO I DO to stop my wife from burying us in piles, starting projects without planning, and generally doing things that impact my routines and actions? I'm a production technician celebrating 20 years this fall, and most of my working career is based on maximizing downtime, estimating how long things take, and being efficient. The small things are what I find most frustrating. Taking the last water bottle that I was going bring to work, piling in front of my dresser while "organizing", leaving her car in the middle of the driveway when I'm coming home soon -the stuff that impacts me directly (unlike piles in our spare room- things that if she thought about, she'd realize impact me. 

I do a large amount of things around the house. My wife will try to take things off my plate, but it usually results in more work for me. For example, I handled the mechanical things and hadn't gotten the lawn mower ready for the season yet. My wife asked me to tell her what to do- via text while I'm at work... Basically, told her the bare minimum - check the oil, connect the battery, fill with gas. She mowed the entire lawn. I needed to do the more complex checks and I discovered she didn't tighten the oil dipstick, resulting in oil absolutely everywhere while she mowed. Not only a mess  but it made the oil very low. She never noticed the splatter everywhere... I've asked nicely for her to focus on her unfinished projects that are in her wheelhouse. If I point out how she misses things, I'm told that I'm perfect and do no wrong. 

I am absolutely at my wits end. I can't see a therapist because we live in a rural area and I simply don't have time between work and home. Someone please tell me what to do, not just what to avoid!
