Dude, don't feel alone at all. We have all been there, and on new waters we ALL still are.
OK, I've been at this for a while but the advice might not be what others might think. This might not be what you're after but bare with me.
Flies
Learn what the real ones are, not the ones that "experts" tell you to use as a "never fail" pattern. One chap on here has so many "prototypes" it would make your head spin.
So find out all you can about the insect life where you want to fish, river or loch and THEN find out what flies will imitate the chosen prey. You might be surprised how small your fly box might end up but then that brings us to...
Fly tying
This is as important as the fishing. Learn slowly how to do this and you will be able to interpretate what you see into what you chuck at the fish. Which leads me to...
Casting.
If you are not confident in what you are doing ASK. There are some GREAT casters on here that can help you. Take a lesson because one hour with a pro (finaar finaar) might just make the difference.
Gunner 100 said that this is not a sport. Top man! This will be a way of life that will suck you in and spit you out some days and humble you and on others it will lift you above the loch. It is not a sport, it is a way of life, that can only improve your life. There is no doubt that the learning curve will be steep. Anyone that says they know it all is a twat. You'll be dead before you've learned most of it, but you will die a happy and fulfilled man.
Dude, enjoy, ask, seek and most importantly, just fish.
Have fun
