@busymomof7 I’ve done a bit of research, first thing I learned is that there are a few different vitamin D assays (tests) and they do not always measure the same thing. The general theme of the article I read was that a better assay for vitamin D is needed.
Second thing is from Wikipedia:
A mutation of the CYP24A1 gene can lead to a reduction in the degradation of vitamin D and thus to vitamin toxicity without high oral intake
Next:
Levels of 150 or greater are universally considered toxic. Ranges of 80-150 are debated as to their likelihood of adverse effects
The most worrisome effect of course is hypercalcemia, or too much blood calcium. The worst outcome of hypercalcemia is heart related as proper heart regulation, in particular heart rhythm, requires a precise blood calcium level. Other effects can include nausea, weakness, frequent urination, kidney damage.
It seems to me (I’m no expert, just researching this instant) that you should be on the lookout for these symptoms and if they occur another vit d level and calcium are called for.
Talk to your doctor about the need to limit vitamin D and calcium in your diet.
Consider a quick visit to a specialist if your vitamin D level rise. Perhaps they say nothing to be done, it’s great your vit D level is so good. No harm done.
Also if your vitamin d level continues to rise could consider genetic testing. I’m not sure how it would benefit you, but it might be helpful to your relatives. I think it might be wise to have your children’s and siblings vitamin D levels checked.
There is so much research and emphasis placed on low vitamin D, it’s unusual to talk about intrinsic high vitamin D.
Perhaps I am being an alarmist. In these types of situations, I feel it’s better to be safe than sorry.
@busymomof7 I found this article. Note it is from 2014 and much research has been done since that time. As an aside it lists a few conditions that cause high vitamin D levels such as various granulomatous diseases (sarcoidosis m tuberculosis), lymphoma, MEN (you can google this, it is a rare disease causing tumors in endocrine glands) and a genetic mutation. The real question I can’t find an answer to is does a vitamin D level of 88 constitute hypervitaminosis. Most of the literature I read states that when high vitamin D levels cause elevated blood calcium fatigue is certainly one of the many symptoms. But I suspect your calcium is normal, or your doctor would be much more concerned.
This article is the first I found stating that elevated vitamin D levels alone can be associated with fatigue. So it is a possibility. So many things cause fatigue. It is a vague symptom. And the possibility always remains that you have more than one process causing your fatigue.
Sorry I couldn’t be of more definitive assistance. The article is a pdf file. I don’t know how to upload it. If you want to read it, go to google scholar. Search:

@busymomof7 that’s the highest vitamin d level I have seen without supplements. Do u take any supplements?I’ve seen a lot of sun worshippers and their vit d wasn’t nearly as high. Do u eat a lot of fatty fish? You are interesting and a bit of an
Egnima. I’m curious and will do a little research
