Hi @Im_so_sorry_okay
Thank you for sharing what is happening for you. Do you experience any distress or negative impacts from fidgeting? Do you know why your stepdad tells you off about fidgeting? It sounds like he is wanting to get you more support.
Unfortunately, we can't provide medical advice on the forums. If you feel worried or unsure about what is going on, you could talk to your doctor or a mental health professional to determine whether it is an issue or not. For example, fidgeting might be your way of managing anxiety and there may be other things that you can do instead that might be more helpful. They can help you decide whether fidgeting is a good thing or a bad thing for you because everyone is different 🙂
I was also wondering if you have anyone in your life that you can speak to about this. Whether it is another parent, a teacher, a counsellor or a doctor?
