From your post, I guess you are somewhere in the Autism spectrum. I would enlarge the case of not being accepted or being kind of different into a family group, any other mental or physical issue.

Parents as a rule, want a perfect child (if this even exists) so there’s a tendency to express this disappointment somehow or another. Obviously, not all parents and relatives are like that but there are still a big group who go themselves like this.

You know what? Autism has nothing bad. I know it’s harder for others to establish connections with people who are like this (depending on the grade) but people is not perfect. Everyone has an issue, this or another nature. It doesn’t mind. The person is over it all.
