Second day of study week...

Today is my second day of study week. But i still haven't started my revision...
Today i have drawn twice for the surveying plan. Why? Is it i didn't concentrate when i draw? Even when i draw the second plan i also write the wrong word. But i didn't dare to trouble my friend to take me another piece of tracing paper. So, i just left it wrongly...
Half way when i draw my second plan, my mummy call me. From the voice i hear through the phone, i guess she is crying because of my sister again... But what can i do? I'm not a doctor or even a magician who can cure her illness. She is going to sit for her test in this coming June and she is having her test in this few day. She felt very stress. But all those stress is come from her. No one give her any stress.
Another thing, i think she is getting ill. She started to still money even though now not only my mummy is giving her pocket money but my daddy also giving her pocket money... Why she do so? Doesn't she know that what she doing is wrong? Doesn't she know that her action will make her family members more hurt? Who can tell me? Who can give me the answer? Who can help me?
The answer is NO ONE!!! No one can help me or her. Only she, herself can help her. Everyone told me that this need to take time, but do you think that she still has time?
TIME? TIME? TIME? Can a person who as skinny as a skeleton spend any extra time to cure the illness that no one can cure? I scared before she can cure herself; her time has come to an end...
