Sorry, I don't really have much faith in enabling-concept. You didn't cause this. Your actions are not a reason why she seems to have so little zeal. You didn't enable her to be like that.
What she does sound like, is that she may have some major mental health problem. Major depression, social anxiety disorder, other anxiety disorder or something like that. Your doing her laundry may not help her to recover from those, but neither would not doing it. She would likely just have dirty clothes, not some major breakthrough to go and wash them herself.
Your taking initiative and doing these things will likely keep her a bit longer out from the streets. They may not help her more. But neither does living in the streets do.
What could help her is treatment for her issues (and no, no one really is like that because they are just lazy, depression or the regression before the schizophrenia breaks out first time for example are much more likely reasons.) And that is a problem. It is very difficult to get an adult to the mental health treatment if they don't want. Some say you should leave it to them to arrange it too, but I disagree with that. Best situation with seriously mentally ill adults I have seen, have been with people, who have been pushed to treatment by loved ones. They have been willing, but parents, siblings or spouses have often had to do the legwork to get them there. They have been lacking initiative, but have agreed to go, when someone else has booked the appointments and physically come and got them to those at least at the beginning. Lacking that initiative is extremely typical with many mental issues, with some it is almost a diagnostic criteria. Unfortunately, if they actively against getting help, it gets very, very difficult. But if you can get her to go, if you arrange it, I would personally do that.
Just my two cents.
