Always analysing deeds: sati and samadhi

In daily Life, I always trying to focus on single good thought so no space for bad. When I did something, I tend to analyse it wether it is good or bad. It is deep most of the time because I am trying to follow five precepts. It seems like I am doing nothing wrong. So I trying to understand deeper clingings (klesha) that are not visible to outside. Most of the time, I am stuck in a loop. But, I recently realize that I'm living in a different world. I am far away from the real world. I was trying to improve samadhi but it weaken the sati. Trying to have a single thought feels heavy to mind. Focus on environment feels calm/less heavy/simple. So How am I improve the situation? I think I have some kind of fear of doing something wrong. Focusing on something good prevent coming wrong thoughts to mind. I heard these kind of advices from monks. But this prevent having sati. Should I have a general idea of good/bad deeds and stop trying to have a single thought always so I can be aware about the environment (have sati)? Have a specific time for a day to reflect about deeds did during the day. Are there any sutta which contrast sati and samadhi?
