If I’m on the autism spectrum does that I’m a failure or a bad kid?

I’ve seen some YouTube shorts and Facebook posts that some moms say that having a kid with autism or on the autism spectrum is awful and just really disappointing, in some Facebook posts I’ve seen or heard about. I feel really bad now after thinking this for a while because I’m on the autism spectrum and not like my twin sister. I don’t know what to do.

Does anyone have any advice on how I can be like my sister?
And is this bad? I don’t know I’m really sorry.
