Hi K.! Wow! You have so much great advice here that I hesitate to add more! I actually have had similar experiences...I am a USMC mother of 3...ages 4,2 & 5mo. with hubby deployed. I actually contacted a natropath because the doctors kept telling me I was fine. There is a connection to Vit. D deficiency and depression...this may be why so many have suggested it...though your levels may be "normal" for a depressed personality, you need more than the "normal" amount. You can supplement or choose foods and beverages with added "D" or simply get out in the sun as much as possible...morning sun is the least threatening in terms of skin cancer. Another key Vitamin that can help battle depression is a Vitamin B complex...especially B12. There are also important minerals you may need as well...they help your body absorb these vitamins. A great article that kind of sums it up is http://depression.about.com/cs/diet/a/vitamin.htm
Exercise is another connection to depression. Keep up on the walking! I know how hard it is to even get out the door, let alone go for a walk! You are doing great...even if you don't feel like you are! Try to walk somewhere at the start of your day to give you energy for the rest of the day. I was so bad I was having problems falling asleep whenever I sat down...I would fall asleep reading stories to my kids, checking the computer...whenever! I got so I could never let myself sit for fear of nodding off. I found that though I am not a diabetic, eating like one is basically eating a healthy diet that is absent of simple carbs and sugars. When I eliminated such things from my diet and chose whole grain cheerios with yogurt for breakfast, or whole grain toast with all natural peanut butter instead of a regular bowl of cereal with milk I didn't have the "crash" an hour or so later. There are "Power snacks" also that can help you...small handful of peanuts, mozzerella chz stick, whole grain crackers, peanut butter crackers, etc. These will regulate your blood sugar levels. I get nausea when I need to get food in my belly...that's when I eat a "power snack". Some suggested snacks worked, and some did not. (Sugar-free stuff make me feel yucky also, so I don't do anything "diet" or "sugarfree" if it has a sugar substitute in it) I haven't totally eliminated sugar...just really regulated exactly how much and when it goes into my body. I saw someone recommended water...proper hydration is sooo important! This can give you more energy and take away your headaches. Pay attention to your headaches. Where do you feel them? Depending on WHERE you feel them can help determine the cause. Side? Front? Where? What type? Throbbing? Stabbing? Your doc will want to know these things! (Or if you lose faith in your doc like I did just look online for a description...look at a natural medicine site for more help on how to help them go away) I also get headaches when I crash from simple sugars. Another thing that is really important is to have the right kind of multivitamin. With my natropath's help, I found the one that was right for me...it took a few tries with a few brands, but I found a good one. Pure Essence Labs is the one I ended up with and all their vitamins are vegetable based. That may not be the brand for you, but as you try them you will know in about a week or two if whatever you are trying is helping. Also, if you do find you have an iron defeciency, take "chelated iron" supplements. This is a type of iron, not a brand. If the iron is chelated, it is vegetable based and cannot harm you. It is possible to overdose and cause yourself harm using other types of iron suppliments if you are not careful. Another thing that has helped me tremendously is taking "Emergen-C" vitamin C packets 2 or 3 times a day. These packets come in a box in the vitamin aisle. I get mine at the commissary...thank God our servicemembers love this stuff and rely on it for all nighters, workout sessions, etc.! As soon as I feel myself starting to crash or feel like I want to crawl into bed with the kids I make up a packet and almost immediately feel close to normal again. I take one as soon as I wake up, around 11 or noon, then again around dinner. Vitamin C packets also will take away symptoms of most seasonal allergies! The packets are my favorite form of Vitamin C because Vitamin C dies so quickly once oxygen hits it. There are many products labeled C but you aren't truly getting the benifit from it. If you drink the drink as soon as you pour the packet into the glass of water, you will feel the difference.
It has taken me a long time to figure all of this out, and as you can see, I have had to make a lot adjustments...but they are worth it. For me it was a combo deal...and there are days when I still have to force myself out of bed for the children...but those days are rare now. Hopefully it is simpler for you! I am interested in what you decided to do, and when you heal yourself, how you did it. If you could post a follow up whenever that happens, I would love to know you are feeling better.
All the best!
