We are all different and fear different things and that goes with pilots too.
i can remember flying a pilot IFR to Ireland VFR he was a great pilot IMC different although he held an IMC rating.
On top at FL080 he could not see the ground, his heart rate was fast and he didn't relax until the cloud broke up past the IOM and he could see the sea below.
Others are as calm and relaxed in cloud as visual
Different horses for different courses apply to pilots as well as the aircraft they fly! As long as you enjoy what you do and fly within your own limits thats fine.
One guy might be happy driving a vintage car at 30 mph along country lanes another might be formula one racing champion. they are still both car drivers!
All I would add to that is practice makes perfect and things you fear as a low time pilot will change with experience and immersion! If you don't push the limits you will never find what lies beyond! Is a great statement and often there is a lot beyond
