Feeling Stuck and Blurry

Have you tried some grounding techniques in those moments? Try to notice your breath, hear the noise around, say out loud what are you looking at and etc.. also it's important that you will notice your doctor if it will keep happening.

This pretty clearly is a form of dissociation, which can occur when you feel so overwhelmed that you disconnect from reality. Separate from depersonalization in that during dissociation, you're grounded in your body but not to the world, whereas in depersonalization, your body is grounded to the world, and your mind might be, but your mind is disconnected from your body.
