Charlie's purpose

Charlie Wright spent all of his life up until this point being part of a team, a twin who never went anywhere without his other half to walk through life with him. But when his twin dies, she leaves him to walk through life alone and Charlie doesn't want to do that without her.
To stop Charlie from trying to take away what precious life he has left, his father thinks it would benefit him to move in with his mother for the time being and take up counselling to try and curb his depression. But Charlie is a stubborn person who doesn't want to be fixed when he feels he is broken beyond belief and his relationship with his mother is far from perfect.
Charlie is never going to be the same and he knows that, he knows he won't be the same seventeen-year-old boy he was before his sister died. But he has to find a purpose in life and keep going for his family's sake.
