I'm 21 and I don't have anything together

I'm in college right now but, I'm in a degree that I don't know if I could get a job for in the future because the market for it is so bad with the rise of AI. I haven't even gotten into the program yet but, I'm debating on even applying because I would have to do extra schooling for it. By the time I'd finish I would be 23 and it would be in a degree I can't get a job with. I was thinking of doing ultrasound tech school right after I graduate but, I was told it would take two years. By the time I finish that and finally have an actual job, I would be 25. and even then, I don't know what's gonna happen to me.

I feel like I'm freaking out about how I have nothing together and accomplished nothing. I constantly see people I went to high school with getting careers and thriving in life while I still live with my parents and fear driving in a car centric city. I feel so embarrassed of who I am and I just don't think I'm meant to be an adult.
