How do I be a parent with disabilities?

I have disabilities but I want to be a father one day but idk if I can, I would get overwhelmed and annoyed so I’d be abusive to my kids without meaning to, I don’t want my partner to have to baby sit me and my kids all day because of me, I can’t do some things on my own without help so it’s not like I can bring my kid to a restaurant and pay on my own and handle my kid at the same time, I have autism, adhd, intellectual disability, I can’t buy things or pay on my own, I don’t know how time or money works, I don’t know math, even if it’s all simple I still don’t understand it, I do want to be a parent one day, I do want to care for my future child, but I fear my disabilities will get in the way it, My disabilities aren’t even severe, I don’t have higher needs, I just have anger issues and get overstimulated easily, how do I cope this?
