I'm a 17 year old student, in their last year of high school and under shared custody of my parents. I have 2 siblings, a 14 year old sister and a 16 year old brother. For nearly my whole life, I've had no problems with my parents. I feel like I skipped the naughty teenager phase, I never went to crazy parties, I've never even drunk (which seems to be especially rare in Australia) Next year I'll be heading to Uni and my grades are good.
My brother is the opposite in every way. We used to go to the same school, until he moved to another school starting year 9. Ever since he was introduced to a new crowd there, he has been in a steady decline. His grades were never perfect, but since changing schools they got worse, and at the end of last year decided to drop out of school and do an apprenticeship. This would have been promising, however he changed his mind and decided to back to school. Now he is in year 11, and has already given up school again after less than a term of it.
I don't know for sure about drug habits etc. (Though I'm almost positive he's experienced it once at least), but the only thing my family can agree on is that his friends are a big factor in this. Late January, after coming home from a holiday trip to Queensland with our, he sneaked out of the house to go to our mum's house. I can't remember if it was actually to see his girlfriend or other friends, but he would claim he had to because our father is abusive to him. In reality, he is spoiled and can't handle having to clean a dish. But opinions aside, he hasn't gone back to our dads house since, and whilst we continue to go there for half the week every week he refuses to move.
Now that he's placed himself permanently at our mother's house, he has started going out incredibly often and spends more time out of the house than in it. Whether it be in the city or down the road we never know, because mum never asks and he would never tell. On some of the occasions we do know, we only found out through letters and phone calls from the police.
This brings me to my mother, who is a nurse working night shifts at a hospital and days at a botox clinic. This busy schedule means she is out of home just as often as my brother, but the difference is she doesn't get to relax when she gets home. My brother has become her primary focus, but she is quickly running out of ideas. No matter how much help she tries to get him in regards to an education and career paths, he brushes it away because he can't be bothered.
I on the other hand, am at home a lot. Apart from school, and the half of the week I'm at my father's, I spend all my time at home. Throughout highschool my social life was low down in my priorities, as life got messy with a divorce and both parents moving house. As a result I'm never out at parties, I have barely any reason to leave the house. So instead of socialising I ended up taking the role of the second parent, mainly at my mother's. As my brother got worse, I got angrier and started trying to punish him, which made both my brother and mother get annoyed at me. It usually ends up in me looking like the obnoxious kid.
As of now I've given up trying to fix him, I've accepted there's nothing I can do, but I still think my mother can do more. Given her lack of discipline and the way she will see him play with an RC car and think he's destined to be an engineer, I've determined she's in a bit of denial about him. She isn't accepting that he is not shooting straight at all, and that given his current streak he would be lucky to only go to juvi. I've tried suggesting to her that he needs discipline immediately, or better yet 4 years ago, but she usually avoids the topic or just says she doesn't have enough time, she's too tired, etc. All of these reasons are legitimate and I'm not arguing them, and I don't even know for sure that discipline is the solution. I'm aware that as a 17 year old I won't quite have the parenting experience of my mother, who has raised 4 kids in her life. However, I feel that no amount of experience can help you to raise a 16 year old ADHD child on your own when you only have face to face contact with him 2 days a week total, plus two other kids. It doesn't help that my sister is a whole other situation, she's been spoiled her whole life and if I were to be honest is almost as bad as my brother, but in a different way. I could write up a whole question about her but I'll keep this on topic.
I know this is more of a narrative than a question and I don't even know if this belongs here, but I'm just desperate to know what to do to get my brother to stop being the reckless teen he is, what my mum should do, or even what my brother should do.
