@zes0460 has a point.
In so many years most people would have made some progress.
But maybe you just have to take a different approach.
In hockey, before you can play hockey, you must learn how to skate on ice.
First learn how to play chess before you play speed chess.
I don’t really believe in puzzles, because when I do them I already know what I am looking for.
In real live OTB games, my opponent is not going to say:” you can look for a fork now, or a skewer situation.” You have to figure it out for yourself what the possibilities are.
Keep playing games, a couple of games a day and try to learn as many as possible from mistakes. I really recommend chess.com lessons. In my opinion, the lessons are well instructed, even for a guy like me who doesn’t speak English. Watch the vids and then do the exercises.
Don’t just move pieces because you have some kind of plan. Also try to figure out what your opponent is trying to do or what he/she can do if you make a certain move.
Follow the basics, like controle the centre and develop your pieces.
Puzzles also seem to really lean towards queen and rooks. If his rooks are getting knocked out early and the queen is lost, the puzzles may not help much.
Stop feeling sorry for yourself, do some research (many good suggestions here already), set up a simple plan, execute the plan.
Oh, one reason you're so bad is that you haven't played me. After that, you'll know what bad really is.
