My 17 year old brother has never been good at getting up in the mornings, but in the last couple of years and especially since September, it's getting ridiculous. My mum can drop him off at sixth form in the morning as it's on the way to her work, but for months now he has often missed his lift as he's still been in bed at 8.30. This means he either stays at home all day or if I, his 19 year old sister, am able to take him, I take him.
He doesn't get up because he claims he never woke up, he was "asleep". This can be despite him nodding or opening his eyes etc when my mum tells him repeatedly to get up, opens his door and his blind. On the odd occasion that he is "awake", he often claims he is too tired to get up.
I want him to get to sixth form because I know that if he doesn't he won't do well in his A Levels, but I'm really beginning to resent him. My mum asks me to take him there if she has to leave without him, which is most days. I've been able to do it for the last few weeks because I'm at home from university. It wouldn't be ideal but I wouldn't mind taking him if he were ready at, say, 9am. But I often have to wait until 10.30 or 11 just to leave the house. He lies on his bed, half-dressed, for ages and ages because he is "too tired" to continue getting dressed. He takes ages in the shower, and often goes back into the bathroom to use the toilet for maybe 20 minutes after he is, finally, dressed.
I'm really starting to resent him because it seems like he just expects me to wait for him indefinitely. Sometimes I have waited all morning until about 11.15 and he decides he's not going that day because it's now "too late". But he doesn't tell me this, I just go upstairs to ask him how long he will be and he casually mentions that he's not going. I've tried shouting, crying, asking him what's going on. Nothing makes any difference, he just ignores me and doesn't answer. My mum says she understands what I'm saying, but that she's had to deal with it for years herself and it's stressful for her trying to get him up too. I'm angry with her as well for allowing him to treat me this way. AIBU?
