Sad, Disappointment and Unhappiness

Finally i understand why all my relationship dont work out. Problems does not lies on me but on my parents esp my mum....she nvr admit the mistake she had done and always think she is right and everyone should listen to her.. I HATE THAT!!! Her practice of favouritism is coming more and more obvious, i tried my best not to think or even recall of the test result but things are getting more and more out of ctrl, they are driving me to a corner and i have so much in that i need to let off but who cn i turn to...no one is wif me when i most need help, nt even he is there for me when things happened, he choose to walk off, i couldnt stop myslef frm asking this question why am i hanging on and what i am struggling for so long, why did i choose to keep my life when i could have give up totally 8yrs ago....why am i still staying alive and who am i doing this for? since no one care abt my existing why shld i make myself so miserable and why am i so stupid to choose to overcome all the problems that i encounter in life, why didnt i let the problems to buried me to death....Why am i being brought into this family that i need to contiune to suffer all this unfairness, since we r not related in any forms, why did they still choose to brought me, they could hv left me alone...why did they give me a family where i dont feel the love and sometime not even belong to the family.....everyone has parents that dote them and love them but why cnt i have such parents. they only see the surface of my wrong doings but have they really sit down down and ask them selves why am i behaving such a way....if they really take me as daughter i wouldnt be going thru all this alone and suffer in silence for so many years...When can i be off frm all this torture....Is it true that the only way to break this off, death is the only solution..to make everyone feel happy.Maybe w/o me ard things will be more happier and cheerful for them..O God, when will you take me out from all this unfair treatment and sufferings i am extremely exhausted...when can i have a complete rest from all this.?????? Haiz!!!!!!!
