Clean and lubricate the gun.
Go shooting with someone who is experienced...if you have to pay someone for a training session do it.
Re-evaluate your choice of weapon and consider getting a revolver till you are proficient enough in shooting to move on to a pistol.
Would be a good idea if your mentor brought a couple of revolvers for you to try.
Make sure you have eye and hearing protection.
You should not be scared of your gun but you must respect it. To some extent being cautious is a good thing. As you develop as a shooter your confidence will grow. Good luck and safe shooting.
