I'm sorry you had such a tough start on this forum. If you give it a bit longer, I think you'll find lots of interesting and helpful people here. When I first stumbled upon POTN, I was just starting out in digital photography and owned a Canon G12. The people here helped me so much with their suggestions, book recommendations, etc.
I seldom shoot in manual mode. I'm in AV most of the time, which means I can adjust the aperture of the lens with my main dial. I usually manually change the ISO to get the shutter speed I need for the shot. Some people like auto ISO but for some reason, I don't. I guess I use AV mode sort of like manual except I let the camera adjust one of the other two points of the exposure triangle.
One other thing I've discovered is age affected my ability to hold a camera still. I have a pretty good holding technique, I think, but I'm not as steady as I used to be. I use a monopod or tripod almost all the time. I got used to doing so more quickly than I thought I would. I don't see as much camera shake in my photos now.
Anyway, you will do what you need to do but giving POTN another chance might just work out for you, over time. It sure has for me.
