Welcome aboard! Im sorry to hear about your parents. It's hard to deal with, especially with little support. But you are not alone. We are all here for you! You make a great observation with the overthinking and disassociation. It's very relatable. I've worked on it for a long time; changing the mindset. It's not easy, but very impactful. Im 40 now; it gets easier, I promise you. 17 is hard, but you're going to get through it. Dm me if you want to know more about changing mindset, etc. I didn't want to go into a rant.
