What should I do about this feeling? I ate waaay too much junk today
Are you feeling sick? What made you think eating a bunch of junk was a good idea?
I don't know, I felt like I was having some kind of out of body experience. It felt so good to just keep eating junk food.
Eating because you're hungry is fine but eating too much of anything is bad for you, regardless of it being junk food. You're likely going to feel sick for a good minute, so for now I would suggest relaxing so you can let it digest.
Why do you insist on lecturing?
Didn't you ask for advice on what to do? I was only giving you a suggestion because of that request. It wasn't my intention to lecture you.
