Help A 15 Buy My First Furniture

In my state, I'm too young to get a job, and I have always relied on my parents for everything. I want furniture for my room ( bed frame, dressers, nightstand, that sort of thing. I would like to get curtains, a bedspread, and organizers. I'm home-schooled with Bipolar disorder, so often I get something called a manic episode. It's different for everyone, but mine means I can't sleep for days on end, and I get quite restless. I do projects to keep these episodes from happening all the time. My current project is furnishing and cleaning my room. I also like to build things, and sew clothes. This is the only project I have ever done that requires a lot of money, and I want to prove to my parents that I'm not helpless and that I can manage to do this. I would be very grateful for the help, as it means I can not only have a wonderful room, but I can make my parents proud that I'm buying my own stuff.
