In your "rebuilding", you'll need to learn to identify "good probability trades" (probability of being correct and risk/reward is favorable)... Price TA is the key to that. You'll also need to develop discipline to take only good trades and to use stops for when they don't work out. (Almost impossible to succeed at trading without discipline.)
Right now sounds like you have neither, but those things can be learned.
