Dont laugh at me

Okay, by the reviews I thought I would like this game… but I cant open the door when you just start playing… i dont know how! Can somebody tell me how to open a door? And my flash light runs out a minute or less into the game, is that normal? I cant pick anything up or open doors so I might just wait and try to figure it out or find a new horror game. So three for the reviews, one taken for not opening and picking things up, and one for flashlight running at into 30 sec of game.
