I also have dyspraxia, here in the states we call it developmental coordination disorder, in addition to level 1 autism and severe ADHD.
What I also carry with me is ptsd from simply being a kid in school. I have an article here on medium, all about ptsd I have just as a kid learning trying to learn to print letters and learning to write. I would try so hard to write, and my letters came out wrong and the paper would tear.
I do think certain types of therapy can help. It sounds like the things they had you do were not the right activities. In the sort of therapies they have here in the states, they talk about the “just right” level of challenge. Physical tasks that focus on just one skill, that are scaffolded with not to much challenge, layered as very fun activities, always with lots of positive reinforcement instead of the negative. Sounds like they just forced you to practice horrible tasks and berated you. I’m so sorry. Dyspraxia is still hard for me. While exercising often trauma of feeling ashamed from my lack of athletic skill still comes up for me. I don’t like gyms, but instead try to find environments where exercise isn’t competitive and there aren’t people staring at me, or judging me. No one seems to care how much I such at my yoga classes.
