Based on of your birth details (subjected to your
accuracy of your birth time):
There is an extremely strong tension in your natal chart
surrounding your individual self component (Ascendant is heavily
afflicted by a T-square aspect, involving planets acting as
significators from 1st - 5th house, stellium in 1st house,
conjunction of all outer planets). Your entity of Self isn't just
tied down; it's glued, bolted, nailed, and buried ten thousand feet
beneath earth, with you struggling to get out from this
incarceration.
I see suppression - (Uranus conjunct Saturn in tight 0 degree
aspect). I am going to explain your situation paradoxically with
this set of irony: Your have an individualistic inner personality
that subconsciously wants to free itself from your subconscious
dimension, by manifesting it in your consciousness and transforming
you as a person likewise. But simultaneously, you have a very
'safe' and rigid attitude towards this transformation because
Saturn seeks to conserve and crystallize this energy from
scattering.
The best analogy I can give you is our PAP government - our
government is maturing at a very slow rate; they understand the
importance of liberty and freedom... on how creativity,
entrepreneurship, arts, etc, will bring Singapore to the next level
of growth, but are not willing to lose sight of the shore.
While others might dismiss your situation as innocuous, to make
matter a little worst, you have a very enervated Mars (in Anaretic
Degree) completely drowned in the sign of Pisces (also part of the
T-square). In simple, your chart revealed personality weakness and
lack of courage to initiative changes or decision that would ruin
status quo. This creates a synergy with the above pointer -
your helplessness
lies greatly with your perception of how futile you see yourself in
changing your circumstances.
However, despite all that, you did not resign to fate (Uranus in
1st house wouldn't easily allow it) - but what happens is that your
quiet frustration and tension builds upon your helplessness and
when the condition are right, it triggers an astrologically acute
depression (Saturn in 1st house, conjunct Neptune are all signs of
depressive outlook in a person). Approximately, your trigger will
occur around:
1) 4.83 years old
2) 12 years old
3) 19.58 years old (I think you just hit (or is hitting) this
currently)
Even if you don't really understand what I said above, it doesn't
matter because whatever I have just said is not as important as
what I am going to say now:
To change your plight, you must first seek the strength to change
from within. Your inner strength is feeble; your desire for changes
never matched up with the action needed for changes to occur. If
you can never see that you are the key ingredient to overcome your
struggles in life, you will always live a life of
suppression.
And that fear will always make decision on your behalf - you never
fully become yourself as a person. 
Cheers
