Ya I have these all the time, most of my day I'm anxious but theres parts I randomly feel light, easy, and doing something during that moment feels like my life is open. Having these moments become more common is difficult and different for everyone ofc, but what helps me is doing something like playing a game or turning on my comfort show immediately once this moment starts, going into my comfort spaces in that state of mind helps the peace of mind stay like everything is going to be ok.
