I'm turning 17 and don't feel adult at all T~T

This is sort of an unusual type of post for me, but I just wanted to yap about it and talking about this stuff to my IRLS makes me feel kinda burdensome. In short, I am getting scarily close to being an adult, but don't really feel ready at all. I'm immature, don't really have many adult interests, and am INCREDIBLY irresponsible. I thought when I got older I would start to care a little!! Well I still don't. Most of my friends have big college plans and know exactly what they want to do yet I'm sitting here 1 not even knowing if I want to go to college or not and 2 if I did go I have no clue what major I would pick, much less which school. I don't have a very strong support system either so I know I need to get my shit together but I am so fucking lazy it's genuinely sad. Guh. Gotta get a j*b next year. Kill me. Even though school makes me low-key wanna die I'm scared if I don't further my education I'll end up stuck in retail. IM NOT READY FOR THIS!!!
