hi
i think for starters it is ok to tell your dad you were wrong and to go see who he suggested. he should not have lied to you - you coul *calmly* tell him that. but then maybe try being ok with getting help.
I think you're right - you do need someone who can see a different perspective than you can. And that is good to know that, accpet that, and take action to get it done.
Good luck with it- let us know?
