Sometimes i wish i wasn't autistic

I'm almost 30 and was diagnosed when I was eight. Even before I was diagnosed I knew something was "different" about me and so did the other children. I was outcast a lot and picked on a little bit. It affected my self esteem but I slowly got over that as I got older and made more friends. However, even once I was no longer bullied by my peers, I've still felt frustrated by how society sees autistic people. I've had to deal with being treated like a child, or alternatively, being invalidated when I mention a symptom. Even my ex did this or said I was "using my diagnosis as a crutch" when I said something triggered my senses.

I started going to therapy when I was 20. My therapist was nice but seemed to infantilize me, like when I mentioned I had a long distance friend (who I video chatted with many times) she was worried I was being catfished because people with developmental disabilities are "too trusting." She would ask my mom to come in with me and ask her questions about me instead of asking me directly. Even my mom has been guilty of infantilizing me, like going to appointments with me when I was working with employment services to find a job, etc. but she's mostly stopped that.

I have a friend who I love but she focuses on my autism a bit too much. She has made appointments for me to get my oil changed and things like that, sometimes without consulting me. She called management at my apartment building when she thought I had bed bugs rather than letting me handle it. She sometimes thinks she has a say in what jobs I apply to, what I do with my time and money, who my other friends are, who I date, etc. and tells my parents if I do something she doesn't agree with. She thinks my ex took advantage of me because I'm autistic, but if anything I've been taken advantage of for being a nice person.

TL;DR: I'm diagnosed with Asperger's and throughout my lifetime I've felt invalidated and/or treated in ways that aren't age appropriate, and subsequently I sometimes wish the autism would just go away. Is it normal to feel this way?
