I wish that I wasn't an only child.?

I'm an only child, and my parents are always being so overprotective over me. They always say that I'm never responsible enough, and in my eyes, I see that I can't be responsible enough, as they've always wanted to spoon feed me everything. I try my hardest to show them that I'm a responsible child, but they just don't seem to agree. I rarely get the opportunity to be with my friends, and my parents feel as if they need to CHOOSE my own friends for me. The people who are my friends are the nicest, and responsible people, and my parents still find the need to judge every single thing. At times, I just get so frustrated that I cry, seeing that most people my age are partying and with their friends, while I'm stuck at home with my Asian parents. I've talked to them, but they still don't want to let go. Sometimes, I wish that I was never an only child. What should I do?
