I’m sorry to hear that you are coming up against judgements and pressure from your parents. It can be challenging to parent such a passionate child! Check out Parent Management Training Oregon Model. I’m not sure where you live but this program is fantastic for teaching parents skills to help them manage challenging behaviours particularly in kids who struggle with ADHD, ODD... or are just really passionate children who like to challenge boundaries. If you don’t live in a community where it is offered there are a lot of articles, books (I think), and resources available online. If you want more info feel free to PM me about it.

It sounds like you are doing the best you can. Your son (and daughter) are super lucky to have you in heir corner. I hope your own parents can find a way to see that too.
