i understand what sub drop is (as well as sub space, but i've never truly experienced neither). however, usually after imagining various scenarios and masturbating, i immediately feel depressed.

is this normal? is it caused because of the realization that i'm alone (imagining a Master reassuring me and telling me he loves me as soon as i start feeling depressed sometimes helps), or is it related to the submissive nature of my fantasies?

has anyone else (alone or with someone else) experienced this, and to what degree?
