thoughts of life

just now went to visit my uncle at hospital. he is having hepatitus C. but is under control. then i had some other relatives who came to visit. my other uncle wife, was saying her younger sister got breast cancer n her older sister got blood cancer. i m like...huh!!!! omg. i suppose they are around their late 40 to early 50. her older sister who got blood cancer, is kinda waiting for the DAY to come only. nothing much can be done. i m thinking, life is so fragile. life is very very short. i m going to be 21 soon. another 20 years more, i will need to start worrying bout sickness. the coming 20 years will be worrying my career and money to support my life. first 20 years of life will be all bout studying. then the following 20 years will be all about work and family. following 20 years will be about ageing and medical check ups and sickness. the remaining years will be all about waiting for the DAY. what is the meaning of life?? what is the meaning of us staying on this earth. how important are we?? we are probably jus a micro nano cell of the whole universe. i always question myself about this. i always wonder our life issit like a game of 'The Sims'. jus that the player of the game is the GOD. even i m only going to be 21 soon, but i dunno how long i can live. probably tomoro will be the DAY for me, probably next month.....i dunno..is there really some thing call the after life?? is there something called the next life?? is there really heaven and hell?? is there really that someone up there?? whenever i think about this issue, i will have this cold shiver. i just wish there is some1 here can hug me tight and tell me, he will be there for me all the time, he will be protecting me all the time, he will go through all the hard time with me, and will share my sorrows with me.
