TS is 17. Moving out will not be until a few years later.
Instead of hoping to move out one day (which I feel does not
address the problem, but instead serves to add on to intolerance of
the situation), TS should be looking at how he can change things at
home.
Some people do not know how to properly express their feelings, and
when doing so, are not aware that the way they behave is hurting
the people around them.
Talking is useless if you don't apply the right method. Think of
better words to use. Is your tone of voice appropriate? Are you
able to be patient and keep your calm while talking to your father
over sensitive issues?
Your dad is the head of the family. He probably has a pride he
feels he needs to uphold. So when talking to him, try to do it in a
way that hurts that pride the least? If you can keep him calm, I
think he will be more receptive to your opinions.
You want to be happy and comfortable, but what do your parents want
for you? Well er, assuming they are 'normal parents' with 'normal
attitudes' towards their children, they hope for you to perform at
least adequately well for your studies. If you can see that your
dad's temper has become worse due to your results, aim to score
better the next time round. If you can show him that you are
capable of being self-disciplined and independent, I think you will
have more persuasive power.
Gently let your father know that his behavior is hurting you. Do
not be afraid of appearing weak - just let him know how you feel,
and what you hope for him to do and what you will do in return.
Don't ask for too much at first, and make sure you keep your
promises.
And then of course... you have to try to talk to your dad more, let
him know what's going on in your life. Maybe then he'll understand
you more.
