I never dated, never had a relationship, never had sex, never kissed a girl, never went out with boys. 19 years old and I don’t know what to do

I never dated anyone, never had a relationship, never had sex, never kissed a girl, never went out with boys. I always stay home alone. I don’t know what to do. I’m 19 and feel like 10 years old. I don’t know how to behave, I’m shy. I don’t know what people like. I’m worried about my future. I have no friends. I don’t go to college, I can’t study well, I’m poor. I don’t have any hobbies. I have too much anxiety and I feel lost. It’s hard to bear this. So, what should I do?
