hey there, i feel you on the social anxiety aspect of things.
but i think one of the less helpful things you can do is compare yourself to what others are doing--to a certain extent. college honestly isn't worth jack shit; i would recommend either a trade or even taking an interest in turning hobbies into some sort of income. this could either be through starting a store, displaying it online (either through photos or even making videos or following video tutorials). or you could start off at a community college and most of the time the bigger universities in the area will transfer these gen. ed credits pretty cleanly. (although make sure your first time at uni after comm. college, you do well because the gpas get a little weird).
it can be hard, especially when you are starting out or struggling with the idea of competency or motivation. like i sometimes i give up pursuing or starting things because i think "whats the point? i'm not any good at this and i feel lost". and i don't know if you struggle with these kinds of thoughts too. sometimes you can power through them and sometimes you'll struggle with them. i'm not very good at powering through them myself these days.
i also struggle with the whole ability to drive a car too. One parent barely knew how to drive and the other only taught my oldest siblings how to drive and my oldest siblings never trusted me with driving to not kill them in practice driving/they didn't have the time. the point is, if you don't have someone to teach you it becomes way harder to get the skills to get a driver's license. i don't know what country you're in, but here in US the knowledge portion is the easiest part but the actual driving part is hard when you haven't practiced or had anyone to teach you. its an expensive option, but there are driving schools. i would suggest that after you've amassed some savings to put towards it.
but if the anxiety is crippling, maybe i would suggest doing some shadow work or asking and investigating yourself what situations give you the worst anxiety and what situations are uncomfortable but do-able. for me, if i have to talk to a "superior" or get asked questions where i perceive it as a "high stakes" situation then i feel that's when my anxiety is worse compared to if i'm outside, walking by myself and listening to music in daylight. but then again, it's probably different for you and maybe all situations put you into a crippling state of anxiety. that's ok, and there shouldn't be any shame in recognizing this.
either way, i hope things get better for you.
