Bedroom organization ideas? Help!!😱

I am VERY ocd and ever since I got a job I have been fixed on the fact that I need to make my room absolutely perfect. I’ve bought new bedsheets, put up a few pictures, a mirror, renovated an old desk, and much more, but im still not there. I have three pieces of furniture that are black and brown (I would like all white furniture) but im not sure what I could replace them with. Two are more like storage containers with drawers. In those I keep extra school supplies that I don’t have room for in my desk, craft supplies, keepsakes, and body care items. They both completely fill up the two containers and it’s all stuff I would like to hold onto. Do any of you have suggestions on what I could use to store all of those items in or a specific store on the cheaper side that has good furniture items? I am also looking for a headboard or would diy one. Any suggestions would help!
