Possible PPPD in 13 year old

I have been dizzy since 2022, and seeing clear-ish grey black lines around tall objects [ like a street light or person] very rarely though, like 3 times in 2 months. The dizzy stuff is like a wane and wax of intensity and time in-between them. They last 1 sec to 3 minutes, it's not vertigo, could be non spinning vertigo. I have the same triggers and symptoms as a person with PPPD [ i have anxiety also] but mine are short. I did go to a doctor and he said it's just puberty??? No explanation, it felt like he didn't care. That was like 2024 and they have gotten worse, I have fallen 5 times and many times stumbled. After a episode my head hurts and I feel dizzy, I can't really say what my vision looks like because I am often too focused on the feeling but I would say that it's like shapes and colors " watercolors together " this doesn't effect my everyday life but it's annoying and hurts, many people don't understand why I will need to sit down or I stop walking. :[ I think it's something vestibular. Thanks for reading.
