Coming from a guy who did 27 months in Afghanistan in a line platoon and has seen just what PTSD can do to people close to me, just remember that you are never alone, and somebody out there does care, even if it's just some idiot from the fishing forum.
As far as your bank fishing difficulties, I like to break down the water into 3 basic levels, you have your top, your bottom, and everything in between. I will usually bring something to cover all three of those levels based on the time of year, frog summer, walking bait or popper in the spring, lipless in the winter, squarebill in the fall, etc, in addition I bring a finesse option of some sort, usually a ned rig, or finesse jigs, something like that, and I simplify my colors to 2 choices, clear water, and anything else, usually this means some kind of green pumpkin/natural color, and something black and blue/bold color, I don't take a skunk very often, may not always catch monsters, but I catch fish most of the time, don't rush to pitch something in the water when you show up, look for the low hanging fruit, obvious places fish hang out, and catch a "warmup" fish, it's amazing how much better a day is when you get the skunk off the boat/bank with you, even if it's just the one fish, might also help to set time limits, 30 minutes on a topwater, if nothing is biting try something else, 30 minutes etc, you stay anywhere more than an hour or so and haven't got bit, change it up, grab your searchbait of choice and run and gun until you get bit, I'm willing to bet either a soft plastic swimbait or a lipless would serve you fantastically this time of year, whichever you feel most comfortable throwing in a new pond, nothing wrong with putting it down and tossing a ned rig at a lay down, rock pile, or other no brainer spot as you pass either, the high percentage spots are nearly always worth the effort, that is why they are high percentage spots after all.
