Whats wrong with teens these days?

[Jae]

I am a 16 year old girl. And I love life, cute things, and I hate seeing people hurt. I thought most people did. But now it seems like everybody my age is going crazy! Theyre obsessed with suicide, cutting, pretending to be anorexic and all of these scary things. I'm a one direction fan (please dont hate me) and so i look at 1D pictures on instagram and i came across ALL this weird stuff. These girls are like calling themselves 'satan666' and that type of thing and theyre posting pictures of the band members where theyve edited them with devils and cut their eyes out and put devil symbols and cuts and scars and stitches and cracks on their faces. Stuff that i cant even unsee. Im really scared and i feel lost and helpless because these are the people who are my generation and who i'll be living with socializing and working with and theyre SCARY! if they love all that stuff when they are the adults in control is it just going to be a demonic killing spree every day? Is this just a phase they will grow out of? please help me or give your opinion. Did people do this back in previous years, just that there was no social media to see it on? Or is this going to be what makes the end of the world? Im nervous and upset about it because theres no getting away from all of them. Its like being in a horror movie ? please help me. thanks

PS what caused this? is it peoples lack of parenting? i knew that thats why kids are such brats but is it why theyre crazy?
Oh okay, so I'm judgemental because I'm afraid the world is going to go downhill when these frightening people get loose in society. I didn't even say anything to them nor am I personally calling anybody out. And being bullied doesn't have a valid connection to the devil at all. Everybody gets bullied so yeah.
I didn't say that Вαиgтαиღ , you don't need to answer based on false assumption. If I thought every teen was like that wouldn't I think I WAS. Please read.
I'm not referring to the VERY few people who actually DO have real problems, like their parents abuse them or things like that. I'm talking about the people who's parents won't buy them an ipad or their 'crush doesnt like them back' who post pictures of them cutting themselves about it or say they want to kill themselves over it.
