Anyone else experience this

I’ve been anal training as well as chastity training for months now. It has gotten to the point to where I where a metal flat cage and the dildos I use are very large. To my point; I have recently (1 week ago) stopped using chastity and anal training because of personal issues. During this time I have experienced an unexpected depression and moments of short temper. Now that I have moved back to chastity and anal training, I am generally a lot more happier. Is there some sort of phycology behind this or is this something to be concerned about?
