Too much vitamin D

Patient: I just started taking vitamin D3 supplements yesterday, I haven’t taken today’s dose yet because I’m a bit worried if it’s too much. I chose to get the 10,000 dosage because I don’t get vitamin D whatsoever. I have depression and I very rarely leave my house, I’m talking like leaving my house once or twice a year; and I’ll be wearing sunscreen during those times. Since I don’t go outside at all, 10,000 daily isn’t too much, is it?
