I can't speak to many of the variables in your current situation, vuedoolor, but this line really stood out to me:
My memory recall, focus, concentration, stress level, anxiety, sleep pattern and cardiac rhythm is really out of whack so I'm thinking about self-medicating with nootropics and other vitamins/supplements to see if I can improve in those areas (so far starting with a multivitamin). Already starting soon on my new diet which is going to mainly consist of veggies and also trying to get the whole family onboard. Other things I really need to work on is being more organize, exercise, and meditation.
For focus, concentration, stress level, and sleep pattern, I recommend starting with meditation. It's free, requires nothing to change except yourself, and a small investment of time can make a BIG difference. There's a free app called Headspace that could get you started today. A few minutes of stillness, breathing, and guided meditation - really, try it for even 2-3 minutes to start - could help more than nootropic drugs, supplements, or vitamins.
While adding vegetables to your diet is always admirable, protein is what keeps your brain and muscles going. You could even keep a jar of peanut butter in your car and have a spoonful before you go in to work and as soon as you get off your shift. Remember to drink plenty of water. When my husband worked the assembly line at Frito Lay, he had a hard time getting to the bathroom, so he cut back on fluids and ended up dehydrated, which is terrible for the kidneys (and can also mimic some of those stress symptoms you describe above).
In short: Drink water. Eat protein. Breathe.
