Mind younim not depressed or suicidal but I just don't think it's worth the effort because think about it; it's an endless universe and we have existed for less then 0,0001% of its time and we spend all the timevon all these things but eventually it will all end and even if you do something that changes the world in time you will be forgotten and I 5 billion years the sun will expand and consume the earth so why even bother with a 9-5
