Vitamin D3 deficiency could cause these symptoms on my Mother?

I think you should stay home. If you feel that unwell, you're hardly going to make a good impression anyway. Believe me, no one wants to be friends with someone who's coughing and sneezing all over them, and they're hardly going to thank you if they catch it.

Going to school when you are sick and not up to it will benefit no one. Wait until you're well. Your cold shouldn't last much longer.

Another week or two, tops. Still plenty of time for you to make friends!

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
