What age should you tell a child or teenager that their parents won’t be around forever?

That is a very harsh reality we all have to face one day. Some people have to keep tell me my parents won’t be around forever because I’m not getting the hint or point so they had no choice but to be blunt with me and that hit me hard. Most autistic people don’t take hints well. Anyways it is kind of hard to explain it to a child but teenagers I think they can handle it right? Truth hurts but they’re strong enough to handle it. People are brutally blunt to teenagers all the time aren’t they? I’m 19 going on 20.

My parents are no longer around and I was told that, “I told you so but you didn’t wanna believe us when we tried to prepare you for life. Hard facts need to be said and heard.” I miss my parents so much. 😭😭😭😭😭😭💔💔💔💔💔💔💔💔💔💔
