Living in the present sounds comfortable and easy when people talk about it. It is shown as peaceful, slow and stress free. But in real life when you try to stay in the present life sometimes it can feel strange. Even it can be uncomfortable. That discomfort does not mean you are doing something wrong. It means that you have started noticing the thing which you used to avoid.
When you stop distracting yourself, the thoughts and emotions which you have pushed aside start coming back to you. The feelings you did not have time to settle now are attracting you. This can feel heavy at first, living in the present is not always soothing, it can be honest as well.
