Saying “it gets better” is a really, really handwave answer - but I kinda want to frame that phrase in a way that, as you go on and grow, you’ll realize that a lot of those negative thoughts you’re having is just an illusion from not knowing the full story…and even if there is stuff in life that will bum you out, as you go on you gain skills at processing it.
I don’t think there’s any two post-high school lives that are ever comparable; for example, I came from a very, very large high school and that circumstance made the shift in social life a little easier. Also, I didn’t have social media after graduating, so it was harder to see where everybody’s lives were going.
But at 19, I was trapped in my town and was really alienated and alone after high school. And it’s a rut, and a crappy time in life…like, the feelings that you’re feeling is valid.
I think what helped me get through those times was exploring my creativity and translating all the boredom I was experiencing into art. That, and I started just throwing myself out into the world and joining clubs and different communities (doing stand-up, activism, going to the art gallery, using Meetup.com meetups) as a way to meet people, and build new friendships that I lost in high school.
Of course, with the global quarantine, that’s a little hard to do right now, but when that subsides I think it will help.
