I started getting floaters at around your
age too. They may be a product of anxiety,
though for me they weren't. Stress can
definitely make you notice them more, so
that's possibly what's happening.
As always, when you notice more floaters
than usual, you should go for an eye test
just to be on the safe side. I have tons
of floaters (among other kinds of strange
things wrong with my vision) and sometimes
I can notice them more than others. That
said, I haven't noticed them in months...
But yeah, get the eyes checked. They can
assess if there's anything wrong very
easily, and you'll feel much better when
they give the all clear.
