When does feet stops growning? I think I have a big feet

I'm 18 years old, and I have a size of 45 sometimes 46 EUR. I have 185 cm height.

I'm thinking that in next years will get even huge and that's depressing. How was your feet at these ages? I wanted to know what's the average for my measurments and age but couldn't find any list on web so I'm asking you guys.

Thanks a lot
