The meaning of your life is up to you to decide. I've questioned myself so many times about our existence's meaning, and I've come to the conclusion that questioning life's purpose too much will just bring you down, it's best to just go with the flow, be happy and try to leave the world a better place, either by changing it or leaving it as it is (sometimes it is the best option). Do things you enjoy, surpass your limits, and after you die, you'll be in peace in harmony with the universe.
Whoever fights monsters should see to it that in the process he does not become a monster. And if you gaze long enough into an abyss, the abyss will gaze back into you
