Now you are at school, what do you do well? You are very tired I? You me hard training? You eat what you got yet?
I hope you are at school you would be fine! If you are tired I would like to ask you to stay, and will need to drink plenty of water, very much.
And to exercise regularly, every day with each and then eat on time.
And when you are at school you will need to take care of their own health, as well. From time to time, you will be able to sleep with warm towel blanket.
Never sick!
