Hi! When I am looking for advice on this online, it is mostly for parents and I'm not a parent I am the one with the autism..
For reference I am level I and was diagnosed a little over a year and a half ago.
When things change for me I get extremely upset. When people cancel plans with me, even if it's calling on the phone, I will get super mad at them and cry and stuff. It has happened multiple times and it is really embarrassing for me and everyone else involved.
Another example is when I was little, my mom would make a schedule of what dinners she would make and I would cry if she made something different without warning me, especially if I was really excited for it.
It is so embarrassing to be so rigid and almost everyone in my life who I care about has told me it has negatively impacted their relationship with me. it's legit so horrible but I can't stop freaking out at these really little things.
