A letter giving advice
Dear Exhausted,
I really understand your problem ! know how terrible to have a very busy schedule Here is some advice that I hope will be of help to you.
First of all , try to sleep 6-8 hours daily reduce your football practice 3 times in a weak or practice at the weekend only
I also I think, it would be good idea to have your lunch with your family to see them. after that take a short nap
It would give you some energy to come back to you part-time job
I hope I've been able to give you a few ideas
Good luck
John
