Eating problems

I've noticed for the past 1-2 weeks or so that I've been eating a ton after school. I just keep eating and eating and eating, and I tell myself to stop, but I can't. I eat for like an hour straight. I don't know if this is a problem or if it's just me. I also have really bad depression and anxiety if that has anything to do with it, thanks for any advice. I'm kinda lost here.
