If I skip my Vitamin D3 supplements, I get harsh symptoms?

I started feeling horrible and like I had arthritis at 22 last year. Finally went to the doctor and my Vitamin D was 12. Doctor started me on once weekly 10,000 IU pills. I noticed a difference, but eventually ran out and didn't think about it.

About a year later, I tore my meniscus moving furniture in my classroom. At 23, I didn't understand why I had so easily injured it, but I'm beginning to think it had to do with my low Vitamin D levels.

Fast forward 6 months and I've been taking 10,000 IUs daily for about a month now because my symptoms came back really bad. I got to the point where I was depressed and suicidal. Vitamin D changed my life because my depression and thoughts vanished within days of taking the vitamins.

I've been off of my Vitamin D supplements for a few days (I've been taking Vitamin B12 because it seemed D wasn't working anymore and I thought I might have another deficiency).

I started getting angry, foggy, disoriented, felt like I was on edge and about to explode, spacey, had flu-like symptoms, and couldn't function to save my life this morning. As a teacher, I couldn't even teach I felt so bad.

I wondered if my lack of Vitamin D this week was the culprit and so I took my usual 10,000 IUs and within and hour, I felt like a different person. The weight of foggy disorientation and the lack of being fully aware/decisive lifted and I felt myself.

Why does Vitamin D affect me so much? How can it affect your brain, muscles, and mood, all at the same time?

It's pretty much fact that the diet and lifestyle of modern humans don't allow for adequate consumption of necessary vitamins and minerals. As such, studies have shown that an overwhelming number of people walk around with deficiencies without even realizing that their issues could be attributed to those deficiencies. The reason why they are so important is because vitamins and minerals, like water, are necessary for our bodies to function. And when you deprive yourself of necessary ingredients, your body gets stressed out and isn't able to function like it should, leading to a host of side effects like you've listed above. Some people have unique reactions to certain vitamin supplements however, so it can be tricky to figure out how to get them in you... I know personally that I cannot take vitamin D supplements because it makes me have serious acne breakouts.
