Are you seeing a T? Is there someone, a family member you can talk to to confide on the issues you're facing?

Could it be due to the fact that since school's out, you're not pretty much occupied as you were during the school term, and thus is feeling empty?

I'm concerned on your binge eating and throwing up, though.. I hope you do know this by now, but it's not good for your body. (something about gastric juices etc etc)

I hope you do find the courage to reach out and talk to someone.
