>>1312First of all, god doesnt burden people with more then they could handle. If your autistic, its a sign of your strength. That you are able to endure not just daily life, but your mental illness.
Secondly, demons are also a creation of god. They cant help you with autism, but they will surely cause you more harm.
Just ask god to guide you to the straight path, and if your a good person and have faith in god and his messangers. Surely life will get easier, and maybe you will go to heaven as well. But only god knows that part.
