Can I snap at my dad after a very stressful past few months?
Why are you going to snap at him?
I feel that I could really use a professional one-to-one talk with him about my problems
It's healthy to bring up issues that are bothering you. You should be nicer about it but still tell him how you feel.
My plan is to snap at him first, if he doesn't give me what I want. Then I might try talking to him later.
Don't you think your dad might be more receptive to hearing what you have to say if you try talking to him first? If you snap at him first it might just lead to an argument.
