I would suggest you to hold onto your love confession her when
both of you are more familar with each other and you know that she
is comfortable enough with you.
Ask yourself this, why would you want to jump down from a block of
flat when you know that you will truly die when you reaches the
ground floor. I know you cannot resist gravity and you really feel
like you want to experience it at least once. Don't be attracted to
failure because it is the easiest event to experience. Instead, see
how you will fail and work out the solution to success. If not, you
will never grow or evolve until the day you die.
I'm telling you, there is flat absolute 100% chance she will
definitely reject you. So go and know more about her first, be her
frd, be her good frd, be her close frd before you even try to be
her bf. 
Anyway, I have never wanted you to die.
