Gaining

I can't be sure but I'd say more liquid stuff instead of too much standard food. For exemple try weight gainer shakes or drink cream, eat icecream, etc. I would also try things that are already fat such as bacon. Good luck and hope you'll make the step

You're welcome! I think so but again I'm not sure. Besides I think you'd have to get really really fat to see your face get bigger from liquids. Usually fat gets first to your belly, hips, legs, ... and once it has stored too much then it usually goes to your face and other places.
If it's the only thing that makes you affraid to get fat then I don't think you have to worry much. Unless you have the genetics making your face blow up when you gain weight. Feel free to message me if you need some advice. I might not be the best but I'm always happy to help
