27 M, Feels like I don't know anything

I am 27 M, working in MNC early 80 k per month. I am kind of nerd and introvert in nature and that's the reason I don't know many things I don't know how to ride scooty/bike I don't know how to ride car I don't know how to bargain I don't know how to cook I don't know how to shop like clothes for myself, I get confused till now I take my mother for the same. Also whenever there is some document related work I get anxiety for eg I haven't made passport yet. And many more things.... I think the reason is I am working from home from last 3 and years which is making me dull, but I can't go to another city to stay because my father doesn't leave with US my younger brother is in college so I need to stay home taking of my family (mom and sis) moreover money is also getting saved. Please suggest how to fix my life. I will take your advices very seriously and try implement it.
