Also check your resting heart rate to see if it's beating too slow or too fast which can indicate a heart problem (about 60-90 is an average bpm but a young teen should be in the low area) I doubt it's serious but it's always best to get checked by a medical professional :).
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.
