Bryan welcome and congratulations!
I am a firm believer in doing the WalMart walk to learn to get more comfortable. It literally consists of wearing your firearm and walking into the store, starting at one side and walking each and every aisle till you reach the other side. By the time you reach the other side, you’ll feel far more comfortable than you did when you first started.
Everyone struggles with feeling “comfortable” the first few days/weeks/months and it may take some people longer to start feeling comfortable than others. I would most definitely say head to a walmart or whatever large store you have near you and walk each aisle. When you first start, you feel like everyone knows and sees your pistol (they don’t). You’ll fidget with your clothes (stop that), you’ll try and adjust (stop that too) and just walk around. You’ll realize soon enough that no one has a clue you have a loaded weapon on your person and you’ll start relaxing and start realizing it’s ok.
Take care and ask us anything you’re curious about.
