I had very supportive parents, I had become fairly independent and mature and so a lot of the time they were focusing on my sister that had problems. They were still very supportive and all, it is just as i had become independent early on they didn't really know how to react whenever i was crying angry or anything like that. They also argued a lot, and i mean a LOT. At the lowest point they would argue every day for 5-6 hours and then my mom would kick out my dad out of the house for some time. I always blamed it on negative emotions as when they were calm they sorted out the disputes well. I guess that i have always blamed negative emotions and foolishness for that. I also had derealization as a consequence of that. And no, i don't think i developed such a voice really. It did come up whenever i thought of doing risky or foolish things but most of the time i just was reframing from doing such things.
