Strong Jew,
If the Tikunim and teshuva haven't worked until now, don't count on them working in the future.
Maybe this isn't a spiritual problem at it's root...
Like you wrote in your previous post
Actually, having analysed these things, I came to conclusion that my laziness led me to temptation, then the temptation turned into addiction. Each fall (and the addiction itself, the fact that I can't overcome it) leads me to depression and low spirit, and that doesn't let me to study well, to overcome my laziness, which is the root of my problems. This is a vicious circle
The tikkunim and teshuva will only be a distraction. There will time to be a tzadik later. Right now you need to focus on developing ways for you to stay away from triggers and from lusting. Don't think about the "destroyed worlds" and the "she-demons".
Think about what you can do to live an "honest" life.
