Hi Hayley and welcome to the world of photography.
My advice is don't get hung up on the camera, pros 10 years ago were producing fantastic images on cameras you can now buy for pocket money.
Lenses are a longer term investment, and there are some bargains to be had, once you've decided on a camera, just check back for lens advice.
More important than all that is practice, shoot anything and everything until using a camera is 2nd nature.
Then you can start thinking about specialising, you'll know what you enjoy shooting, what you're comfortable with and what interests you.
By the time you've settled, you'll have gone through a lot of gear and a lot of hours sat at a computer learning.
If I told you I wanted to be a chef in an Indian restaurant, but had never cooked a meal, let alone an Indian one, and I'd never actually been in a proper restaurant, you'd say I was daft.
Keep the desire, push yourself, be open to ideas, learn the basics, there's loads of technical as well as creative things to get right.
You'll have a ball, but your first camera? Is just that; the first, if you take this up, there'll be many others.
