I can relate to this. A few years ago I was a 30 year old guy who felt like a feeble 70 year old. I was tired, depressed, and just didn't feel well at all. I had a blood test and the doc was flabbergasted at how low my Vitamin D levels were. Technically I had rickets! But then I started taking 10-15k of D3 a day and in a couple of weeks I felt great. Now I take 5k in the summer and 10k in the winter and haven't a had a problem since.
So, moral of the story: get your Vitamin D levels checked. And take D3, not D2.
Same here, add poor circulation to the list of symptoms. I no longer have perpetually cold feet. I had to have my GP refer me to an endocrinologist though. The endocrinologist spotted it right away. Super cheap to treat. Been taking it for about ~6 mos.

Especially if you work indoors or otherwise avoid sunlight. (I don't take special pains to avoid the sun. I like the sun, but I do avoid outdoors when it is too hot, which is most of the time in my area.)
Exactly how I felt! I'm 31 now myself. I'm really hoping my experience is like yours, because I'm still not 100% myself again. Currently 2.5 weeks in.
I can't even imagine what my levels were prior to taking the 500% RDV supplement I was on before having my blood checked. But at <9ng/ml, I most likely have osteomalacia.
All doctors will only prescribe D2 (ergocalciferol); so you really need to go and get D3 (cholecalciferol). Your body naturally produces D3, and the latter is much more bioavailable. Because of this, you will also want to scale down your dose and not take as much. It's possible to go too far and end up with hypervitaminosis, which ironically can also cause random bone pains, and calcification of your arteries.
It's important to test your 25(OH)-D levels every few months when taking extreme supplements.
Also, be sure you are getting enough calcium and magnesium. These are the chemicals needed to maintain healthy bones. Doctors do not prescribe the magnesium, and large vitamin D supplements will deplete this, also leading to calcification and other problems.
Finally, for anyone living north of South Carolina, you will not receive enough UVB radiation from the sun to produce sufficient levels of vitamin D during the winter months, and milk really has very little vitamin D. So you might want to test and possibly supplement if you are experiencing random musculoskeletal pains. Low levels are fairly common, and usually not a huge deal. But at my level, it was fairly severe.
Out of curiosity, why do doctors only prescribe D2? It sounds from your description like there's essentially no reason they shouldn't be prescribing D3, and yet apparently none do.
A doctor did advise me to take D3, though she's an unusual one, far more helpful than my official insurance-provided doctor. I don't know what the official one would've prescribed, because none of them even considered testing for it.
So, moral of the story: get your Vitamin D levels checked. And take D3, not D2.
