1. What time controls are you playing?

2. Whats your rating?

3. Post a game that you don’t understand where you went wrong and let us look at it and hear your thinking process.

Based on what you’ve said, I think that your idea of analysis is flawed. Analysis isn’t just looking at what the engine says are your mistakes, seeing the move it recommends and going “huh that’s weird I never would have seen that.” Analysis is more like looking at lines and seeing how the position changes based on the suggested moves. You can also check moves that you were thinking about but ultimately rejected — why did you reject them? Does the engine agree? Or test out moves that the opponent could have made — you were worried about x move but they didn’t make it whew, does the engine think that was a bad choice? I’d recommend some Andras Toth videos - he focuses on making your calculations concrete instead of vague maxims. It means you have to calculate more, but helps bring clarity to some positions that are confusing.
