Turning officially an adult in a few days

Don't even know what to say, doesn't matter anyways, I just wanna rant lol, in a few months I'll be in college too, I feel weird to be honest, like, I'm quite mature, but, not enough to be an adult... I've changed, for good I think? Doesn't matter, I'm just worried about life in general, always been, and, almost everything, feels rotten, shallow, find solance in few things, mostly in genuine human relationships, and, that's what worries me, been long time since I've opened to new people and I'm still somewhat afraid. That's all, guess I just needed to take out what I had pent up, thanks for reading if u did.
