is your father support's you??

Both parents should support ALL their children without favourites. I find it sad that your father is treating you this way. ALL parents should practice positive encouragement. Being happy and praising you when you do good work and absence of praise when you do something wrong, perhaps with advice on how to improve. Unfortunately I have seen many aprents, mainly mothers, who ignor etheir children until they do something wrong and then shout at them. The child learns that the onlyw ay to get attention is to be naughty and you can see what happens. I hope your father will read this comment and maybe reconsider his approach.
