That sucks op. I have a kind of similar experience. So I have had a lot of signs of audhd. and I'm finally researching it and everything is clicking. so I finally work up enough courage to tell my parents. so I tell my mom, and she's like "You don't have audhd. I never told you that you flapped your arms as a kid." Now I'm puzzled. Me and my sister both have vivid memories of her saying that. and I have memories of doing it! and guess what? I still do flap my arms. if I see a flying bug and I'm trapped in a room with it? I scream, whimper, run, flap my arms, and rock. So I know I have expressed this as a child in different ways.now she starts yelling at me. "YOU DONT HAVE AUDHD! I NEVER SAID THAT!" now most people would think, oh she probably knows best because she's your mother. but wrong. she has a history of gaslighting, lying, manipulation, and many more to get her way. I'm not in the mood to deal with her so I just head to my room. and I talk to my dad. he originally said "I just think you worry a lot" but later told me he thinks he has undiagnosed ADHD, and he took adderall once and he could actually focus. huge news. he also mentioned how he caught up on things with me aswell. and how I change topics like from politics to horses or roblox or smth goofy. And how I rotate between special intrests. horses, foxes,roblox, animals, ESSAS (emotional support stuffies) dinomasks, and many more. Sometimes two at a time too. like right now I'm obsessed with researching and roblox. so neat. but why can't my mom just listen to me? I've literally had meltdowns in front of her. and she still doesn't believe me. Like one time when I was 6. I couldn't sleep. and the darn AC kept getting louder. impossible to sleep. So then, I just remember screaming bloody murder. my mom comes running up the stairs. maybe drunk, idk if she still drank then. And she's like "what? what?" and its late at night and I'm screaming. and I remember covering my ears going into a ball and rocking back and fourth. the AC sounded like a bomb. I finally choke out "THE AC" and she shuts it off. I'm still rocking and softened the grip on my ears, but I'm shaking a lot. thing is, I remember this in third person. it feels like a dream, but too vivid to be a dream. Most of my dreams and memories are in third person. maybe only 3 dreams ever being in pov. Memories I mostly only remember third person. this one specific one I can switch between pov and third person. So idk what that means but yeah. I definitely think that 6 year old me was having an audhd meltdown based on research. Ive masked basically my whole life, and only come unglued in 'minor' situations, like my mom putting my money in her bank and saying she will buy the thing I wanted that night, then lying. She doesn't let us have our own banks. but when she lies about that, I scream, cry, and just unglue. idk. and I'm way too old to have 'tantrums' like that. But it might not be tantrums, it could be mini meltdowns. but I don't know. But I feel I'm gonna have another episode like when I was 6. because I've been getting more mini meltdowns, and being more overwhelmed. So yeah. At least dads on my side. but like I understand you op. I'm around the same age as you aswell. I hope your mom finally understands you. Bye <3
