It feels like I don't want to think anymore

I am a person who loves everything that involves logic and deep thinking. I am a huge fan of maths and science and anything that causes me to think. To sum it up, I derive pleasure from thinking logically, step by step and concluding. But recently things haven't been the same for me. It feels like I do not want to use my brain anymore. I work as a software engineer (graduated last year) which I am not enjoying, to be honest. I work out 3-4 days a week, do yoga and maintain a healthy diet. So it seems like nothing is wrong with my physical health at least. But I am never fully present in the moment anywhere. It is like watching time flow and doing nothing. Like I am living my life on autopilot. I like to read books and watch anime. But I have been struggling to read the last book I picked up and I cannot get myself to watch the anime that I had started watching and had found interesting. All I do is just put on some show so that I can have some background noise.

Has anyone else had the same experience? What did you do to get out of it?
