Replying to Very Frustrated

So I got a MacBook Pro, knowing that they are good for editing photos and videos, and those are two of my big hobbies. However, I'm not willing to drop the money to buy these programs...I didn't originally realize how ridiculously expensive they were. So now I have this really advanced computer but nothing making it worthwhile. Anybody know of any cheaper editing programs or a way for me to get reliable versions of Photoshop or Final Cut for cheap?
