Hello Diehard_89, I guess you are just a person living in a
wrong environment. Hmm...well, quite a number Singaporeans are like
this...so I'm not surprised at all. One thing you need to
constantly remember is...nobody owes you anything and every person
is for themselves. You probably expects people to help you when you
are in trouble, but think about it by yourself...since when is the
last time you helped somebody/anybody and without any motive
involved?
Sometimes the problem is like this, nobody will help anybody for no
good reason unless that person is really that nice. I'm not saying
that such people doesn't exist, but it would be very rare to bump
into one nowadays. 
So probably the people around you are all not the kind of nice
people that I've mentioned. And don't feel disappointed about it to
a certain extent and start to adopt their mentality and behave like
them. Be yourself and hold on to your beliefs, I'm sure you will be
able to find somebody who will be able to help you sincerely. But
make sure you appreciate them if you do ever come across
one...okie?
I guess for the time being, just forget that you ever had any
friends in school for a while...if it will make you feel better.
Hmm...probably this stage of you life requires you to be
independent in your own learning and also to realise that you
cannot rely on anyone to help you in your life. You will probably
faced with more similar disappointment like this in the future, but
I can ensure you that you will only become stronger once you have
overcome this obstacle in your environment. Until you have
successfully overcome it, you have to be prepared for this kind of
similar situations to keep coming back to haunt/test you.
I felt that life itself is a learning cycle, as long as you haven't
overcome something...it will keep coming back to twist you in a
different way everytime. Even I'm going through some form of twists
in life right now...hehehe...have yet to overcome it though.
^_^"
Anyway, just to let you know that this is not the end of anything
and don't feel so upset about it. If you have to feel bad about it,
give yourself some time to get over it and please get over it after
that period of time...say 1 week max?
Oh yah...as for those people who contributed to your
disappointment, I can only say that they will keep behaving like
this till the day they die. Ever wondered why some older people
behaved childishly and some wisely? There is a huge gap difference
between their thinking and acceptance to life itself. Anyway,
choose to be those wise ones before you grow old. You have a choice
to be who you want to be when you grow old...so don't disappoint
yourself on this one yah.
Good Luck.
