Please help me with my haiirrrr??? thanksss ososososososo much!?

I have brown, curly hair. And its extremely thick. I mean THICK! It's not like ringlet curly, but its pretty curly. So I have no idea what I even want, but I want it to be different than it is now. Maybe less, curly and more wavy? I dont know. I straightened it today, and it was fine, but i just felt like it wasnt me and it was missing something. I dont want it to be completely straight, but I dont really like my natural curl. I want it a different kind of curly. What are some styles I could do. My hair is very long. Like, to the middle of my back, but im willing to get a cut or grow out, so tell me alllll ideas please. What can I do? And if you could, pleaseeee include a picture so I could really see what the style looks like. Thanksss sooooooo sooo much. Im just 14 and Im not good in the beauty part of life. haha thanks again :-)
