Looks like you're not far from Violet City, so if you're able to get there da Pokémon Center should have food and a wahm place to crash until you can get yahself squared-away.

[Joey points up at himself.]

Dat's pretty much what I've been doin' since I came in here, but I finally got enough cash to be able ta crash in a hotel now so dat's a win. I'm way far away from where you're at doe, so I'm afraid I can't do much for ya right now... sorry.
