I'm a single mother with four children - a fifteen year old daughter, a seventeen year old son and eight year old twin girls. My ex-partner, the former twos father, is currently living abroad with little to no contact. The girls I am ashamed to say were a product of a one night stand but I am please asking for no judgement here. Well...I don't know how to start this. I suppose I'll just be frank. My son and daughter have always been very close, and my son is very protective of his little sister, sometimes to a violent degree. Frequently he has been in serious trouble at school, thrice even suspended due to a whole range of different "defences", including swearing at teachers, bashing up her bullies and threatening her boyfriends. He also gets into much trouble unrelated to her. Thankfully he has been able to avoid any real trouble with the law but we have had some very close calls. He is a really smart kid though, I mean really smart (he read The Prince, Caesar's Commenteries, The Art of War, and a whole host of other ridiculously advanced titles at age ten, and was interested in advanced physics and computer science from age five) and great at sports. He used to be very outgoing and popular, but ever since year 9 he has been a bit of an outcast due to increasingly strange and hostile behaviours which I am sorry to say I ignored in the vain hope they would get better. They did not.My daughter on the other hand has always been very sweet and dolice. My twins are wild, always running amuck outside but she always preferred to stay inside watching documentaries or playing with dolls. They were always close, forever playing together, and as they grew older often in close contact eg. cuddling on the couch and at the time I always dismissed this as normal. As she grew older she became more rebellious, I think in part because of her brother's influence, but nothing serious. Anyway the two of them went out for an afternoon walk around 3 o clock yesterday (they still haven't returned) and so I was cleaning in my daughters room. While making her bed I found a sparkly notebook, obviously a diary. I know it's wrong of me but I have always been nosy so I just couldn't help myself. Besides what secrets could a 15 year old girl have right??? It started off ordinary, just talking about gossip and school. But then around thirty pages in things took a terrifying turn. She started talking of feeling depressed, wanting to hurt herself. Like a fish I was gutted. I had no idea.
