I'm 18 right now and honey, if i told you what i did as soon as i turned 18, you'd blush lol.
But so far (my birthday is in april) i took time off after graduating high school. i wasn't mentally ready to throw myself back into school so soon so im taking time and now that i'm ready, currently applying to universities hoping for the best. I've also looked for jobs but that hasn't been a success so if I don't find any by summer, I'm giving up and throwing myself fully into school once I get in.
That's all i've done really. That and hang with friends and discover more about myself I didn't know before and go through some pretty tough family/personal stuff. Sure it's not been perfect but I always try to stay happy, bright, positive, and grateful for everything because even through the darkness, there will always be light
