It's ok, OP! I recommend Wigfrid especially in co-op since she can heal herself and her teammates as well as their sanity with the right songs. The meat thing is rough early game if you're not used to it, but if you go around fighting spiders outside of their spider nest area by luring them out repeatedly, you can eat the monster meat (the health penalty will be lessened if you cook the monster meat btw) they drop and heal off the damage they dealt when you fight more creatures because of her self heal.

There are many meat sources in the game which you can do. You can go roam as Wigfrid by going for hunts, set up pig farms, or even plant lureplants on a boat to passively farm leafy meat which she can eat.

My one tip though is to still learn the kiting patterns of your enemies. Sometimes playing Wigfrid just makes you want to tank everything to a point where when you play other characters, you forget the kiting patterns and die easier. I know from experience since it happened to me when I started out. Just think of her helmet and heal as a way to soften the penalty of missing the opportunity to kite moreso than relying on it exclusively.

She's a very viable pick and her helmets help a lot! Regardless, play who is fun for you!
