You don't need anything specific… It's not some snowflake that you need to take extra care of certain parts. And you don't need to go in depth like to clean out your magazines every time. Just every once in a while is good.
You might want a pick to get by the firing pin block though. Tight spaces and all.
The dirt you dig has to go somewhere. With the sandbags or a dirt mound you get a higher wall without digging as far and you can always pile extra dirt outside your wall of sandbags for concealment. Without the sandbags you have to move the dirt you dug farther away or it can fall back in.
Dug dirt can be a different color and stick out by itself too.
Nothing has to be by itself.
Was the 9mm a small gun? Were the jams with just the .22?
The answer for the rifle is an AR-15 and it sounds like you could be just limp-wristing the 9mm. If it wasn't a full sized handgun try one because I don't know anyone who isn't perfectly fine with 9mm out of a full sized handgun, especially a steel framed one.
.22s can be finicky and small guns snappy.
The way that rimfire is primed and how cheaply it's made leads to inconsistencies. Like there can be voids in the priming compound in the rim that has it not go off. Then the very low power can cause semi-autos to be more particular with ammo and care.
That's not accurate for trying to aim. You should be able to get 1/4 that size.
It depends on the wording of the law and if they're going to change it. Whether it's involuntary commitment or commitment at all or even just taking pills. I can't say as I'm not from NC. Involuntary commitment means you have to be taken there by police or a court (ie not going to a doctor to seek help).
It sounds like you just want someone to talk to so you might get some guidance and meaning in your life. For that you don't even need to go to your doctor.
