Anyone Have Baby Advice?

Hello, all. So to start, I should tell you I'm autistic, have got a few delays, and DO NOT like children. I'm just starting my second ever job that doesn't pay enough to move out, especially in this economy. I don't think I would be able to handle that anyway, because again I'm autistic and don't really have any support systems to help me in the way I would need. Anyway, my older sibling (they/them) has decided they want to get a sperm donor. At first I was excited, but then i realized it wouldn't be the same as when they weren't living with us. When that decision would have nothing to do with me or have any impact on my life. But they are living with me so that decision will have in impact on my life. I don't want to be unsupportive, but I really cannot stand being around kids or babysitting and I feel like that would be the expectation since we are so close. I don't know how to communicate to them the anxiety and stress I'm feeling without them being defensive and unempathetic. My biggest thing is I feel like they are going to deny this has any effect on my life, even tho it does simply because we live under the same roof and are close as siblings. I feel like they're just going to say they don't care how I feel. Again, I want to be supportive and in no way am I saying they shouldn't go through with it, but if it goes through I need a way out of this house or out of this world, because I don't know how to handle all these changes that are happening so quickly. Also, they want to give birth in our living room for money reasons, and I have told them that is something I will not be there for as it seems like it will be a loud and high stress situation. They took that well. I just don't know what to do.
