Politics, racism, lgbt, religion, websites, crimes, war, biology, all of it doesn't matter at all.
If you think something matters, just ask yourself why does it matter?
Keep asking yourself why and you'll come to a place where you can't answer that question.
The paint drama stuff, I don't care anymore.
Abortion being legal and/or right or wrong, doesn't matter to me.
Losing another friend and/or relative, I give no f's.
Being invaded by a foreign nation, give me a reason to care.
Unless someone or something can change my life in a way that would make me care, I am going mostly silent on every platform I use.
I have no good outro ideas, doesn't matter though. Bye!
Nihilism is rather pointless. Sure, we're doomed to die EVENTUALLY, however, we kinda have to make the most of it. Nihilism only works if you have no purpose, and that's not even meaning it would work for you. It is a rather pointless idea unless you are to die very shortly, and not in enough time to do anything, and even then there are often still reasons to live for that short time.
Otherwise, I would advise picking yourself up. If it takes you becoming mentally insane to keep yourself from the whole "it doesnt matter waaaAAAAAH" thing, then do it. If to try for no other reason, try to spite those you hate. If you do not have one you truly hate, gain some enemies.
im not entirely sure how to help u, tho for temporarily that can help. of course, most things if left out of hand will become a bad habit, altho in ur case i have no reason to believe such will happen
