Amateur picture taker, please guide me in buying a camera

So I recently got interested in taking pictures and capturing moments, I happen to find it therapeutic.

I currently take pictures with my nexus 4, could you vergers advise me on what camera to start with, though I currently have a preference for SONY.

Even though I'm just starting, a camera that's great for amateurs and not-so-amateurs would be nice, something I can grow with.

Thanks once again guys!

And Happy New Year !!!
