I don't think there's a thing wrong with what you are describing. I have had the same experience at times in my life and wondered about it. Interestingly, in me, it doesn't seem to be related to depression load,as I am very depressed at the moment and there is not a thing on the planet that could currently get me to cry (except my kids, of course). I am just numb to everything. So, my take would be that it is a positive thing that you are feeling things. That's being a human. Onward!!
