Scared of driving manual cars

Hi everyone I'm going to get my license this year and there's a fear I can't shake off.

I am scared of changing gears on manual cars.

Like growing up here in Europe (and up until this day) I barely go on cars because we never really needed one, so my experience with cars is limited.

I try to see how the changing gears work, but how do people know when to change it and what movement to do???

I love driving and I'm not scared of it, just this thing on cars that make me so anxious I'm going to get stuck or hurt
