Welcome to the "Wrapped Club" at Healing Well! I'm sure you're right--your youth will definitely make the recovery a lot faster. As far as eating goes, everyone is different. A lot of people will tell you to stay on liquids because that's what their doctor told them, or they had difficulty swallowing anything else.
However each of us has unique ways to heal and our eating needs will vary. I went with my surgeon's recommendations, and started solid foods after 5 days. I enjoy eating, and weeks on liquids would have been really hard for me. He tells his patients that they can eat anything that can be chewed to a liquid. Of course that puts a lot more responsibility on you, to follow those directions and not try to eat things you shouldn't.
If your doctor allows these types of foods, take small bites and chew carefully and long. You'll find crackers and toast will chew to a liquid, but bread can't. If you're chewing something that doesn't cooperate, just have a napkin handy and discreetly get rid of it. Don't try to swallow it anyway. Also, you'll want to pay attention when you're eating, or you'll forget and swallow something you shouldn't.
Mashed potatoes aren't always easy to get down in the beginning. Crispy crackers, on the other hand, can be chewed to a complete liquid and are no problem. Bananas can be kind of sticky and can give you trouble. It's variable, and you'll have to experiment.
Good luck with your recovery. Listen to those who have recommended that you take it easy and give your insides time to heal. This type of surgery leaves your outsides pretty unscathed, and it's easy to think you're all healed. Your GI tract has been dramatically changed, and it will take time to heal.
