Why does life feel so meaningless sometimes?

[rawr]

Sometimes life feels so unbearably meaningless and pointless out of nowhere. I could be having fun and all of a sudden my will to live drops. I've always felt this way even as a kid, and whenever I feel it, I just get depressed. Is there anything I can do about this? Is there a reason for this?

Because it is

Because it is

I mean yeah life is depressing but you dont realize that as a kid, especially because even with the problems i had i never really cared too much about them or even really noticed them

So why did i feel this way even when i was younger?
