I kinda wanna reinvent myself, what hair should I choose?

First off, you're a pretty girl and your hair suits you! But if you want a bit of a change, why not get a few foils in the top, maybe lighter than the colour you have now, and have a few layers cut in? It would be noticeable but not drastic (it's never a good idea to do something really drastic when you're feeling a bit down, trust me!).
