Hi:
A neurologist once told me:
You can lie to your family, wife, teachers, boss, etc. but you should NEVER lie to your doctor.
If your concern is them "telling" on you, they can't because of privacy laws. If your concern is judgment, they have probably seen it all...
You are very young and you will get better if you make the needed changes.
Stick around here, we will support you.
Ps: I would also say, we shouln't lie to anybody
