This morning, he insisted to have breakfast with me. I was still in the process of waking up, so I didn't want to be bothered; he didn't want to understand that, and he eventually told me he regretted having as many kids as he did after I told him to leave me alone for a second. When I told him it was just wrong to start throwing that kind of stuff at me especially that early in the morning, he went on a tangent about how I need to face the truth, and he said I was on a slippery slope that would lead me to an inescapable state of isolation and depression like the one my elder brother allegedly is in - by the way, everything's going OK for him, my dad just antagonizes him all the time and uses him as an image of failure.
When I went back to my room, he eventually came in and tried to "apologize" by making up some bullshit interpretation of what he could have meant in a positive way. But I know him well enough, when he starts using the kind of argument he had used, it always means he's really pissed at whoever he's talking to.
So, not only did he essentially say he wishes I didn't exist so he could stop having to care about me, but he also tried defending himself for saying it instead of actually apologizing. Way to ruin my day, dad.
At least, the rest of the day was crappy enough for it to make less of an impact in the long run
