Too Much Thought Watching

Is there such a thing as ‘watching your thinking too much’? There are days when I feel I am watching my thoughts so much, I miss engaging in the world around me, miss engaging with the people in my life. Sometimes, I find myself so introverted that I almost feel I’m just floating along in my day rather than actively participating in my day. Today is a perfect example. I spent time this morning thinking about my mom(she passed a year ago) and then thinking about my relationship with my husband (which is good, but I don’t think we are connecting well right now). I had my day planned, and I got those things done. I got the kids from school and spent time with them. But I feel like I shared space with everyone, rather than being with them. Now, I feel I wasted my day. Even though everything was crossed off the plan. Am I missing something?
