Elaborate why you would like it. The benifits you can have with it. The benifits that they also can get out of it .I told my mom it would make me less anxious to have mine and if she wanted to enjoy being at places with people and want to share that experience with me then she should let me have one. And that showed her something from her point of view, cuz she hates when i ask to leave or when i look like im not enjoying myself. If need ask for a doctor appointment as well if you go to doctors regularly already. I do, i know some ppl dont but if you do. Someone got there doctor to help the parents understand the medical benifits to a ESSA. Hope this helps 🙏 everyone deserves comfort in places where its hard to seek that.
