i'm 18 as well and had my tonsils & adenoids out on the 31st of july. it was an emergency because i had another abcess forming and i had tonsilitis as well. (not the best senior year in the world haha)
i'm almost up to 2 weeks now. the whole scab thing is pretty gross... if you feel it coming, you may be able to spit it out, but usually you swallow it and die a little for a second because you realize how nasty it was (it doesn't hurt, but it's kind of disgusting to know what you just swallowed). after the scabs come off, your throat will be a little raw, and a little bleeding from day to day will occur (nothing major...unless you look back there with a flashlight, you can't really tell). it stings a little and my ears and neck are pretty sore as well, but they have me taking percocet which helps tremendously. tylenol isn't bad either, but at night it's easier to take the more powerful ones so you don't wake up in an intense amount of pain. eating and drinking stings a bit for a few days after the scabs fall off, and your throat will still have a little bit of white in the back, but nothing like the scabs. it might be a little pink/red and swollen from irritation.
eating soft food isn't as hard as i thought it would be, especially with the scabs gone. sometimes food gets stuck back there, but you can drink to flush it out with water or even "suck" it out.
i really hope you're doing well!! i promise you, when you're almost at two weeks you'll feel so much better. just drink a lot. it actually feels better to swallow after constantly drinking.
hope this helped you out!
