I have to ask why you are even attending a university - how did you get
there.

How did you get there?

Oh, you didn't ...

At 19 if you can't do things for yourself already then there is no hope if
you're realistic about it. Is this post for one of your psychology
studies? Post a stupid question, see who responds and then analyse the
results? Seen it all before, they all appear at the same time each year
together with the "help me to design" requests.

Why is it a stupid question?

Did YOU know everything at 19?
