I'm 19. I fell out with my 12 year old sister a few days ago, and it reached its high point yesterday. We had a big fight, which I wasn't soley responcible for, but obviously me being 7 years older does make it my fault. Last night someone got into her msn account, and I'm being blamed. My parents don't trust a single word I'm saying. Today, mum's almost totally ignored me and she's gone off with my sister for the afternoon without telling me where they went or anything. This evening, I took my dog out in the car somewhere, and when I came back dad's car had gone. About an hour later, he came in with a McDonalds - for everyone but me. I've been feeling a bit left out today anyway, so I threw a bit of a strop. He said he'd tried calling me and it wasn't his fault (I never answer the house phone, he had my mobile number and never bothered to call it). But he never accepts things are his fault, so started shouting at me for how childish I am. We had a huge falling out, with me acting very immature and turning the tv up full volume just because I knew it would annoy him. I've been crying now for almost an hour, and they're all still telling me everythings my fault, I'm really immature and I need to grow up. I don't know how to react to these kinds of situations though, it's all built up inside me that noone actually cares and so I suppose I do this to get some kind of reaction outof them, a caring reaction... Which I don't get,ever. I don't know what to do now, I can't apologise because my dad'll only throw it back in my face. I can't talk to him because he'll just tell me how much of an ungrateful immature selfish child I am. Even when I do nice things he doesn't appreciate it, it's how he is. Whats wrong with me? Why can't I react in a adult manner? How do I react in this situation again? Guess I'm just looking for a bit of advice on how to deal with these thigns, because I feel like complete rubbish now and it's entirely down to me.
