As a parent, I'm prepared for my AS son to take a little longer acquiring those independence skills. They are definitely much harder for him than schoolwork is. I know he won't have them by the magical age of 18, or probably even 22. So, we'll have to adapt as a family accordingly. Exactly how, who knows - we'll cross that bridge when we come to it, since I think his feelings on how things get done will be important.
Hopefully your parents are patient and understanding and willing to help you with the skills you will need. I believe you will acquire them - just in your own time and in your own way. So you need extra guidance for a longer period of time - it isn't a big deal, as long as you and your parents are prepared for it.
