is there are people that like to be alone???

as for me.... i like to be alone.... and i feel disturb when people are try to know and care about me... i did not like it... i feel that i like to all people to forget about me.. when my birthday comes.. i always feel empty and i always want for people to forget about my birthday.. cause i feel nothing special about birthday... when my friends celebrate and do suprise me on my birthday.. i just can't feel happy and touched.. absorblutely empty... and when new people want to know about me.. i just hate it.. i dont want anyone to understand me.. cause anyone would not can understand what i really feel..there also people that can see the truth me... as example, "at outside u smile but in inside u are actually sad"... i feel that people is being annoying like them understand u....
