Do we have a choice or our life already destined?

Dear Human Beings,

Iam just a normal man living a normal life but this life carries many things upon it, it has pain, joy, love, hate and after all it's just death which we will all fate with no doubt what matter we do, i was wondering do we realy have a choices in our life, or it's just everything already known and disteny applying it's law over all humans.

I never find the answer for that and iam sure i'll never know not in this life but fate is also strange in a time it brings a large amount of joy and happiness , then suddenly like bomb it destorys what it just built for us and sometimes we thing and we find that we has no hand in that thing, we were simply well driven by fickle fate which sometimes makes me the happiest man in that world and the other time it makes me wish if i were never born, but after all i know that my life is short and i'll live it by a way or another.

please write to me what do you think about our life and if we have a choice or no.
