The mall sounds like the best place to go from here. You nod sagely, remembering that about 60% of zombie movies and/or games involve or take place in a mall. You carefully avoid remembering that of those 60%, 90% entailed most or all of the people involved dying. The mall has food, drinks, weapons, and all the games, animu and mango you can carry. The mall is objectively the best choice.
As far as escaping goes, there are the people at the graveyard, and the people at the church. Neither of them are leaving at the moment, so you should have some time to get some supplies from the mall. You turn around and start heading in the direction of the mall. It was opposite the direction you were going, but it's not that far, so it isn't that much of an issue. You should probably look into getting a map.
At this point in time, the zombies are little more than an annoyance. There are maybe 10 every block, so it's easy enough to walk around them. However, due to your boredom and the fact that there is nobody (living) to see you, you begin dodging them dramatically.
"HOO-HA!" You yell, as you leap away from a zombie 3 yards away, swinging your sword like a maniac.
"You think you are fast? I will show you the secrets of the Lovely Beam!"
You take a dramatic pose, sword brandished, and advance upon the zombie, who is shuffling towards you at a breakneck crawl.
"The secret is this: It is neither a beam, nor lovely."
"TAKE THIS! LOOOOOOOOVELYYYYYYYYY BEAAAAAAAAAAAAMUUUU~!"
You stab the zombie in the face.
"Let your sins wash away in the flow of the love rays," you quote.
