I want my parents to pay for stuff
Do you really want them to pay for your stuff?
Yes, I don't want to ask them
You should be building towards financial independence. It's not nice to just ask for money.
I'll try and ask anyways, and get over my fears of that first.
Asking for money makes you sound dependent on them, they will still think you are a child. Bring yourself to get a high paying job so that they come to you and ask for money instead.
