baby shows autistic symptoms because of me?

Mom, I'm feeling really distressed... I often find myself yelling at my baby (11 months old) without realizing it. If he accidentally spills something or does something frustrating, I tend to yell at him without thinking. I know this is wrong, but I don't know how to handle it on my own. I'm exhausted from cleaning the house and taking care of the baby. Lately, I've also been letting him watch TV a lot because I feel like I can't get anything done otherwise. But recently, I've noticed my baby acting strange... He rarely makes eye contact and seems afraid of me... he's the same with other people too. He cries more easily. His development seems to be slowing down. He doesn't talk as much (even though he used to babble "mamama" and "bababa"). Could this all be because of me? I've read that symptoms like these are related to autism... Am I the cause of my baby showing signs of autism? 😭😭😭😭
