Tad - first of all, what are you currently doing to treat your depression? Make no mistake, this IS depression, and you need help to heal your brain from its biological effects. Are you taking any medications or supplements to treat depression? What is your diet like? Levels of vitamin D, thyroid, testosterone?
Second, you commented on losing weight and wondering about diabetes. If you have diabetes serious enough to be causing weight loss, there should be sugar in your urine. If you won't or can't go to the doctor, at least go to the drug store and buy some urine test strips that check for glucose and ketones.
(And congrats on kicking the soda habit, it's terrible for you, and might actually be the thing that is allowing you to lose weight now).
Also look at a book by...
AS for living paycheck to paycheck, look at the Mr Money Mustache website for ideas on controlling your costs.
