I'm the same age, and I know exactly how you feel...my grandma was just diagnosed with bone cancer, and she's in her eighties, so she wouldn't do the chemo, and she's probably not going to live more than a year. Reach out to your friends, talk to people, don't bottle it up, that's the worst thing you can do to yourself, talk to your grandpa, come up with a plan for what you will do after. Whether that means an agreement to remain an alcohol free house or you going to live with a friend and his parents, it'll be up to you.
You can do it, your grandma will always be with you, and you'll only get stronger(: just always keep in mind that your grandma would never want you to be upset or scared or worried, you just have to take life as it comes, and do what your heart tells you...nothing in life is worth doing if it doesn't make you smile(: feel free to email me if you need it, i'm always here to help...good luck!
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.
