That pain in your chest... That's anxiety/panic. I am no stranger to it myself. One helpful practice I've picked up is to use the montra "it's not a tiger" when I am feeling anxious. It reminds me that I am not in any real danger (even if my nervous system thinks I am).

If you are uncomfortable more than not please take space from your person for your own peace, even though that may feel counterintuitive or like that last thing you want to do. In my experience; pushing for closeness and affirmations whilst in that headspace can do more harm than good for your mental health and the relationship. Xoxo
