I was in the same shoes as you lately but I am 35.
But you are young and able to learn new things and knowledge faster, so as mentionned before it is a matter of repeating physically but also mentally every drill, maneuver, flow over and over.
And most importantly it's about decision-making + situational awareness.
You are about to get that step by step and build up your confidence gradually.
Keep it up elvispilot !!!
