I am alone

I have come to singapore for half a year , Although I did miss my family , but I always feel alone . Recently one of my friend tell me that her boy friend break up with her , because he does not want to get married . I am twenty years now , 21 one month later . Surprisingly I am a graduate student at NUS , even the ungraduate student in our lab is older than me / So , do I need to find a boy friend ?
