how do people still have a life after hs without going to college and stuff?

before I start, apologies for any kind of rambling in this post, I'll try my best to not do so and stay consistent as possible.

Hi I'm a high school senior graduating in May, I do have some ideas on what I wanna do after high school, my main ones being pursuing community college and then a university to major in fashion design and move into an apartment with my best friend. However, I'm worried that won't happen so soon or even at all. Fortunately I am working a part-time seasonal job that I heard I would most likely be kept around due to me working hard, I have a strong friend group, and lastly, I do pretty ok and well in school so it's not like I'm going to have a extremely hard time getting into a college or trade school.

So far things aren't looking too bad however, I'm struggling on; making a portfolio for college (mostly because I don't know how to make a good one that's structured right), I don't have a savings account, I don't have a driver's license, nor do I know how to drive at all, I haven't applied to a lot of scholarships and colleges(which I'll admit that it's pretty much on me but I know it ain't gonna be easy pursuing a higher education with what's going on in America), I'm shy yet socially awkward(not bad to the point where I want to hide from the world but I'm not a social butterfly), and finally, I'm planning on legally changing my first and middle name... Yes, I have done a bit of research on it but I'm having a hard time finding where and how to start the process. I wouldn't mind too if I don't go to college and get an apartment with my bestie right away, I would more so mind if I end up being some friendless and jobless disappointment of a loser, eating junk food and talking to degenerates on discord and going on rants on reddit. Really scary just thinking about that honestly, having everything I've built and achieved going down the drain? Girl I'd be better off dead just so I don't continue living a depressing life like that lol. Even though I'm not a complete introvert, I still sometimes struggle socializing with people like most of my relatives and it doesn't make it better that I'm not good with cues and anxiety being biting me on the ass most of the time too. I guess it's just my diagnosed autism wanting to make itself apparent haha

I don't expect any comfort or advice, though I would appreciate some advice. I just need to express what's been on my mind and to see if anyone is experiencing a similar thing too.
