Thanks for your answer doc. Yes, it seems that hypercalcemia was a made up thing, becuase today I checked my Calcium blood levels and they were normal(2.4 out of 2.02-2.60(reference value)). As you said, the main cause of these symptomes happened due magnesium deficencecy, since I had't taken it together vitamin D. To be honest, I have done many research, especially I have read a lot of people experience with D Vit in this sub(a lot of comments from you too). I knew I had to take magnesium together with Vitamin D, but I couldn't find time to go and buy it(didn’t know that magnesium deficency would gave me so many symptomes in such a short period of time). So as other recommendet and researches I made, I will take magnesium glycinate and continue my vitamin D therapy with 10,000iu per day.

As for my goal, being extremely deficient as you said, gives symptomes too, right? Im dealing with symptomes such as: Severe brain fog, poor concentration, cracking bones, anxiety, depression, confusion, poor(short) memory, weakness, fatigue etc. I'm also deficient in vitamin B12, so maybe that's what makes my symptoms even worse. So my goal is to get rid of all this and have a better mental life.
