Do you think I am immature from what you see in my replies? ?

I have seen your posts before and you strike me as a very nice mature person.  It is hard not to be rude to some people on YA because some of them aren't very nice.  Overzealousness isn't that bad of a quality if it is zealousness generally to be good. It seems you have a lot of obstacles to deal with so only an immature person would say you were immature.  None of us are perfect. People on Yahoo Answers forget that the rude and mean comments they make are to real people and they would never say things to them like that in person.  .  

You might be frustrated for not having a nice boyfriend around. OR it might be that you haven't been able to get an admission in the institution you liked most.  Such things do tell upon the health and cause depression which leads to anger and frustration.  Talk to some expert counselor and therapist.

Welcome to the real world, that's just the way it is.

Not at all ! Anyone who can think oneself of being immature must not be imamature at all , but from your head portrait I can see that you are a really pretty girl, maybe sometime be self-willed,it`s okay,in China it is called princess-ill,but remmber a little is cute,too much then still an ill,will annoy the others,as be immature.Sorry for my poor English!

The world and the reality is not only what  you  know until now.

You are an annoying little girl who denies the facts I give you and does not respect my opinions. Yes, you are a kid. No, you are not an adult and you have to wait two more years to be. Nice day kid (that offensive word again)

Overzealous and rude, gets mad easily, certain people annoy you...yup, get ready to hate adulthood if you're gonna stay that way 🤔

That you felt compelled to ask, ranting about other people claimed shortcomings, does indicate immaturity.
