The problem with pomodoro is eventually you learn that its a trick just to get you started, so your brain eventually goes back to just wanted to never start again.
No technique works without enough genuine desire and motivation to accomplish whatever it is you're aiming to accomplish. (And the belief that you actually have a chance of accomplishing it.) If things like Pomodoro or similar aren't working, then the next step is to figure out if you believe in the path you're on, and are motivated enough to continue on it.
