I don't have any experience with having one, but it sounds like possibly they could help you in the areas you will accept help. Then once you know what you need to succeed in those areas your assistance from them would lessen, until you might not need them at all.
You are only 24 now, I would not worry about being 30 or what may happen then. Even if you try to plan it, it is full of unknown possibilities. Things will look a lot different to you then.
The support worker may even be able to help you access options that will give you more freedom and independence from your parents if you qualify for certain programs.
Let us know how it goes, and if you feel better after they answer some of your questions. Good luck!
