Who should I believe? Who knows me better?

I was hoping to have peaceful dinner however it wasn't at all peaceful. My parents are discussing about my education since I had mention that my maths tutor is unable to teach me at the current moment and might or might not start teaching next year. 

My parents are discussing about tutoring class and if individual teaching or class teaching is better. They both have opposite view and everything. My mum believes that an individual teacher is better than a large class a small class is ok as well. My dad thinks that if a teacher is teaching a larger class is a better teacher which lead to what I have to do in the future. Once again my dad want think I am more suitable for nursing while my mum thinks otherwise. So far my options are either nursing what  my dad suggested , teaching what my mum suggested, engineering what my sister suggested or commerce/accounting which is what my sister did in uni. This doesn't bother me cause I am given a wide view of my options and what is good for me. However what I hate and angers me the most is that fact my dad has believes that all I am can do is nursing nothing else. He doesn't think that I have the ability to teach or the ability to do any other occupation in the entire world. 

I hate my dad point of view. I hate how he thinks that I have no ability. I know that I have no good qualities but I though parents are meant to support you and believe in you. What kind of parent is he? He does not know how to be a good father and that is how he got my sister to hate him so much. He is not a good husband otherwise there wouldn't be so much consistent argument. He is not a good man cause he doesn't have any good qualities. NONE. 

I feel like am useless. I feel like I can do nothing and you know what slowly I am believing that I am able to do nothing in my life. I can't do anything. Maybe he is right. I can't do anything and maybe all my future holds is being a nurse that I know in my heart that I don't want to pursue in my future. I don't know anymore. 

I HATE THIS FEELING. WHY MUST THIS STUPID LION RUIN EVERYTHING? WHY MUST HE BRING ALL THIS NEGATIVE THOUGHTS INTO MY HEAD? WHY CAN"T YOU GUYS LET ME DECIDED MY OWN FUTURE? AS THIS IS MY LIFE THAT I HAVE TO GO THROUGH NOT YOU NOT ANYONE ELSE AROUND ME? 

I need an escape. Someone take me away from this horrid place and never let me return. I don't want to feel useless. I don't want to feel like I can't do anything. But now I really think I can't do anything. 

I Want To Escape~~~
