I ran over my iPhone 5

I now have a crack near the top 1/4 from left to right. It mostly seems to text fine, but a couple of words were detected and misspelled things. The scratch looks light and not deep so far.

Should I go to Apple to repair it? Could it be damaged internally? Cost? Buy a new phone?
