Is it normal to 'overthink' about lost games before sleeping?

As the tile said, for the last weeks I have found myself overthinking about games before sleeping. I would go to bed, close my eyes, and go over the lost games and why I lost them (I'm around 1050 elo, so there are lots of things still to learn). For example, last game I wanted to rush CA with Mongols... In feudal age. Then I learnt I could create them in castle age, so I should have gone scouts, or knights, etc. Something similar with Cumans, I wanted to forward a siege workshop but I had to build blacksmith first. These are the things I 'learn' before being able to sleep. The thing is, is this normal? I don't think it is affecting my mental health, I love the game and I really like learning. But I considered uninstalling it. Any thoughts?
