They clearly have enough background to understand the complexities of human nutrition, but most haven't studied it at all or kept up with the research. It's like asking an ophthalmologist about bladder cancer -- they just don't know.
Consider speaking to a registered dietitian, who actually are trained in this area.

If you take 7000 IU it might take years for you to slowly develop vitaminosis. Get your blood checked regularly to keep track.
Vitamin D is fat-soluable and not flushed out by the kidneys. It sticks in the body fat and therefore accumulates.
Bodily regulation typically happens before synthesis after sunlight exposure but if you take already-complete vitamin D, a hormone, then no regulation can keep a check anymore as you have effectivly bypassed it.
7000 IU might be fine for a while but I'd definitely keep track of the values and if there is medical evidence that higher is necessary for hypothyroidism, keep kidneys and other values in check.

You’re almost certainly taking too much for the long-term. Vitamin D accumulates over time and the half-life is measured in weeks. You may not be overdosing right away, but you can slowly end up in an overdose condition after months or years. It can take weeks or months to reverse.
High dose Vitamin D is only helpful for short-term use to bring levels up into the desired range. After that, you need to switch to a more reasonable maintenance dose like 2000-3000IU.
Even the most vocal pro-Vitamin D advocates aren’t taking as much as you are.
Your hypothyroidism isn’t an excuse to take more. You need to adjust the thyroid issues through thyroid medication, not attempt to micromanage downstream vitamin issues with overdoses.
If you still don’t believe me, please just get a blood test every 6-12 months for Vitamin D and calcium levels. The long-term effects of chronic overdose could be worse than whatever symptoms you were trying to address in the first place.

- If you have gene that will metabolize caffeine fast then you reap health benefits of antioxidants in the coffee and it's good for you
- If you don't have gene that metabolizes caffeine fast then caffeine will linger in your system and cause all sorts of problems and therefore coffee is bad for you
At this age there is no other option except for testing and seeing what works on you and maybe see what your parents did.

As an anecdote, about half a year ago my sister-in-law's 4 year old found some vitamin D pills and ingested what was left in the pack, in total around 60k IU, hours before anyone noticed.
The doctor said to just avoid giving him any other Vitamin D for the next few months and it should have no consequences.
Luckily it was just Vitamin D, pretty much any other pills she had would have probably been deadly at such a high dose.

I do have hypothyroidism too, and my Vitamin D levels are always low.
The first time I got checked (about 3 years ago) my Doctor was impressed with the result, it was unquantifiable. It was waaaay to low. I got 20k/Weekly for 8 weeks and was back in the normal range.
A few weeks without Vitamin D supplement later and I'm very low on Vitamin D again. So more Vitamin D supplements.
I'm not taking it regularly yet, but I can feel the difference. Number one must be not being as tired, number two is sort of like... more content? I just feel better and healthier and a lot calmer.
If there is an actual link between hypothyroidism and vitamin d levels I would be interested in other stories.

I am currently taking 7000 UI daily, because medic told me to do so, thing is... even the same medic, sometimes told me to take another dose, because he forgot I was already taking it, when I told him what I was taking, his reply was... "huh... that I think is about right".
My experience with other medics weren't better.
Also some were AGAINST me taking Vitamin D, because 7000 UI is viewed by many medics as toxic, but I have hypothyroidism, and one of its issues is that some people show vitamin D deficiency symptons even with correct blood serum levels (and the symptons go away only after forcing the levels go higher than normal), telling that to medics also resulted in mixed results, some said they would read more, some got mad at me, some agreed with me.
