I understand your frustration - I have been experimenting with PSE for about the same amount of time. I often feel like beating my head against a wall and yet for some reason I can't stop
However I do feel like I have made some progress. The only advise I can give is (basically what I have tried) just trying one thing at a time. If I can't figure it out, I use the online Adobe tutorial and/or I ask for advice here - the responses have been very helpful. Seems like once I figure out one technique it gives me light into the others. I also have started writing down little hints I figure out along the way because they make sense at the time but I know if I don't use it in a couple of days I will be starting from scratch.
Best of luck - I can only assume it will get better

but the journey is fun (and addictive).
